  text: The environment changes constantly at various time scales and, in order to
    survive, species need to keep adapting. Whether these species succeed in avoiding
    extinction is a major evolutionary question. Using a multilocus evolutionary model
    of a mutation‐limited population adapting under strong selection, we investigate
    the effects of the frequency of environmental fluctuations on adaptation. Our
    results rely on an “adaptive‐walk” approximation and use mathematical methods
    from evolutionary computation theory to investigate the interplay between fluctuation
    frequency, the similarity of environments, and the number of loci contributing
    to adaptation. First, we assume a linear additive fitness function, but later
    generalize our results to include several types of epistasis. We show that frequent
    environmental changes prevent populations from reaching a fitness peak, but they
    may also prevent the large fitness loss that occurs after a single environmental
    change. Thus, the population can survive, although not thrive, in a wide range
    of conditions. Furthermore, we show that in a frequently changing environment,
    the similarity of threats that a population faces affects the level of adaptation
    that it is able to achieve. We check and supplement our analytical results with
    simulations.

  text: Escaping local optima is one of the major obstacles to function optimisation.
    Using the metaphor of a fitness landscape, local optima correspond to hills separated
    by fitness valleys that have to be overcome. We define a class of fitness valleys
    of tunable difficulty by considering their length, representing the Hamming path
    between the two optima and their depth, the drop in fitness. For this function
    class we present a runtime comparison between stochastic search algorithms using
    different search strategies. The (1+1) EA is a simple and well-studied evolutionary
    algorithm that has to jump across the valley to a point of higher fitness because
    it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm
    and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population
    genetics, are both able to cross the fitness valley by accepting worsening moves.
    We show that the runtime of the (1+1) EA depends critically on the length of the
    valley while the runtimes of the non-elitist algorithms depend crucially on the
    depth of the valley. Moreover, we show that both SSWM and Metropolis can also
    efficiently optimise a rugged function consisting of consecutive valleys.

  text: Adaptation depends critically on the effects of new mutations and their dependency
    on the genetic background in which they occur. These two factors can be summarized
    by the fitness landscape. However, it would require testing all mutations in all
    backgrounds, making the definition and analysis of fitness landscapes mostly inaccessible.
    Instead of postulating a particular fitness landscape, we address this problem
    by considering general classes of landscapes and calculating an upper limit for
    the time it takes for a population to reach a fitness peak, circumventing the
    need to have full knowledge about the fitness landscape. We analyze populations
    in the weak-mutation regime and characterize the conditions that enable them to
    quickly reach the fitness peak as a function of the number of sites under selection.
    We show that for additive landscapes there is a critical selection strength enabling
    populations to reach high-fitness genotypes, regardless of the distribution of
    effects. This threshold scales with the number of sites under selection, effectively
    setting a limit to adaptation, and results from the inevitable increase in deleterious
    mutational pressure as the population adapts in a space of discrete genotypes.
    Furthermore, we show that for the class of all unimodal landscapes this condition
    is sufficient but not necessary for rapid adaptation, as in some highly epistatic
    landscapes the critical strength does not depend on the number of sites under
    selection; effectively removing this barrier to adaptation.

  text: Dispersal is a crucial factor in natural evolution, since it determines the
    habitat experienced by any population and defines the spatial scale of interactions
    between individuals. There is compelling evidence for systematic differences in
    dispersal characteristics within the same population, i.e., genotype-dependent
    dispersal. The consequences of genotype-dependent dispersal on other evolutionary
    phenomena, however, are poorly understood. In this article we investigate the
    effect of genotype-dependent dispersal on spatial gene frequency patterns, using
    a generalization of the classical diffusion model of selection and dispersal.
    Dispersal is characterized by the variance of dispersal (diffusion coefficient)
    and the mean displacement (directional advection term). We demonstrate that genotype-dependent
    dispersal may change the qualitative behavior of Fisher waves, which change from
    being “pulled” to being “pushed” wave fronts as the discrepancy in dispersal between
    genotypes increases. The speed of any wave is partitioned into components due
    to selection, genotype-dependent variance of dispersal, and genotype-dependent
    mean displacement. We apply our findings to wave fronts maintained by selection
    against heterozygotes. Furthermore, we identify a benefit of increased variance
    of dispersal, quantify its effect on the speed of the wave, and discuss the implications
    for the evolution of dispersal strategies.

  text: Mutator strains are expected to evolve when the availability and effect of
    beneficial mutations are high enough to counteract the disadvantage from deleterious
    mutations that will inevitably accumulate. As the population becomes more adapted
    to its environment, both availability and effect of beneficial mutations necessarily
    decrease and mutation rates are predicted to decrease. It has been shown that
    certain molecular mechanisms can lead to increased mutation rates when the organism
    finds itself in a stressful environment. While this may be a correlated response
    to other functions, it could also be an adaptive mechanism, raising mutation rates
    only when it is most advantageous. Here, we use a mathematical model to investigate
    the plausibility of the adaptive hypothesis. We show that such a mechanism can
    be mantained if the population is subjected to diverse stresses. By simulating
    various antibiotic treatment schemes, we find that combination treatments can
    reduce the effectiveness of second-order selection on stress-induced mutagenesis.
    We discuss the implications of our results to strategies of antibiotic therapy.

  text: Evolutionary algorithms (EAs) form a popular optimisation paradigm inspired
    by natural evolution. In recent years the field of evolutionary computation has
    developed a rigorous analytical theory to analyse the runtimes of EAs on many
    illustrative problems. Here we apply this theory to a simple model of natural
    evolution. In the Strong Selection Weak Mutation (SSWM) evolutionary regime the
    time between occurrences of new mutations is much longer than the time it takes
    for a mutated genotype to take over the population. In this situation, the population
    only contains copies of one genotype and evolution can be modelled as a stochastic
    process evolving one genotype by means of mutation and selection between the resident
    and the mutated genotype. The probability of accepting the mutated genotype then
    depends on the change in fitness. We study this process, SSWM, from an algorithmic
    perspective, quantifying its expected optimisation time for various parameters
    and investigating differences to a similar evolutionary algorithm, the well-known
    (1+1) EA. We show that SSWM can have a moderate advantage over the (1+1) EA at
    crossing fitness valleys and study an example where SSWM outperforms the (1+1)
    EA by taking advantage of information on the fitness gradient.

  text: The behaviour of gene regulatory networks (GRNs) is typically analysed using
    simulation-based statistical testing-like methods. In this paper, we demonstrate
    that we can replace this approach by a formal verification-like method that gives
    higher assurance and scalability. We focus on Wagner’s weighted GRN model with
    varying weights, which is used in evolutionary biology. In the model, weight parameters
    represent the gene interaction strength that may change due to genetic mutations.
    For a property of interest, we synthesise the constraints over the parameter space
    that represent the set of GRNs satisfying the property. We experimentally show
    that our parameter synthesis procedure computes the mutational robustness of GRNs—an
    important problem of interest in evolutionary biology—more efficiently than the
    classical simulation method. We specify the property in linear temporal logic.
    We employ symbolic bounded model checking and SMT solving to compute the space
    of GRNs that satisfy the property, which amounts to synthesizing a set of linear
    constraints on the weights.

  text: "Frequency-independent selection is generally considered as a force that acts
    to reduce the genetic variation in evolving populations, yet rigorous arguments
    for this idea are scarce. When selection fluctuates in time, it is unclear whether
    frequency-independent selection may maintain genetic polymorphism without invoking
    additional mechanisms. We show that constant frequency-independent selection with
    arbitrary epistasis on a well-mixed haploid population eliminates genetic variation
    if we assume linkage equilibrium between alleles. To this end, we introduce the
    notion of frequency-independent selection at the level of alleles, which is sufficient
    to prove our claim and contains the notion of frequency-independent selection
    on haploids. When selection and recombination are weak but of the same order,
    there may be strong linkage disequilibrium; numerical calculations show that stable
    equilibria are highly unlikely. Using the example of a diallelic two-locus model,
    we then demonstrate that frequency-independent selection that fluctuates in time
    can maintain stable polymorphism if linkage disequilibrium changes its sign periodically.
    We put our findings in the context of results from the existing literature and
    point out those scenarios in which the possible role of frequency-independent
    selection in maintaining genetic variation remains unclear.\r\n"

  text: Understanding the relation between genotype and phenotype remains a major
    challenge. The difficulty of predicting individual mutation effects, and particularly
    the interactions between them, has prevented the development of a comprehensive
    theory that links genotypic changes to their phenotypic effects. We show that
    a general thermodynamic framework for gene regulation, based on a biophysical
    understanding of protein-DNA binding, accurately predicts the sign of epistasis
    in a canonical cis-regulatory element consisting of overlapping RNA polymerase
    and repressor binding sites. Sign and magnitude of individual mutation effects
    are sufficient to predict the sign of epistasis and its environmental dependence.
    Thus, the thermodynamic model offers the correct null prediction for epistasis
    between mutations across DNA-binding sites. Our results indicate that a predictive
    theory for the effects of cis-regulatory mutations is possible from first principles,
    as long as the essential molecular mechanisms and the constraints these impose
    on a biological system are accounted for.

  text: Variation in genotypes may be responsible for differences in dispersal rates,
    directional biases, and growth rates of individuals. These traits may favor certain
    genotypes and enhance their spatiotemporal spreading into areas occupied by the
    less advantageous genotypes. We study how these factors influence the speed of
    spreading in the case of two competing genotypes under the assumption that spatial
    variation of the total population is small compared to the spatial variation of
    the frequencies of the genotypes in the population. In that case, the dynamics
    of the frequency of one of the genotypes is approximately described by a generalized
    Fisher–Kolmogorov–Petrovskii–Piskunov (F–KPP) equation. This generalized F–KPP
    equation with (nonlinear) frequency-dependent diffusion and advection terms admits
    traveling wave solutions that characterize the invasion of the dominant genotype.
    Our existence results generalize the classical theory for traveling waves for
    the F–KPP with constant coefficients. Moreover, in the particular case of the
    quadratic (monostable) nonlinear growth–decay rate in the generalized F–KPP we
    study in detail the influence of the variance in diffusion and mean displacement
    rates of the two genotypes on the minimal wave propagation speed.

  text: Crossing fitness valleys is one of the major obstacles to function optimization.
    In this paper we investigate how the structure of the fitness valley, namely its
    depth d and length ℓ, influence the runtime of different strategies for crossing
    these valleys. We present a runtime comparison between the (1+1) EA and two non-elitist
    nature-inspired algorithms, Strong Selection Weak Mutation (SSWM) and the Metropolis
    algorithm. While the (1+1) EA has to jump across the valley to a point of higher
    fitness because it does not accept decreasing moves, the non-elitist algorithms
    may cross the valley by accepting worsening moves. We show that while the runtime
    of the (1+1) EA algorithm depends critically on the length of the valley, the
    runtimes of the non-elitist algorithms depend crucially only on the depth of the
    valley. In particular, the expected runtime of both SSWM and Metropolis is polynomial
    in ℓ and exponential in d while the (1+1) EA is efficient only for valleys of
    small length. Moreover, we show that both SSWM and Metropolis can also efficiently
    optimize a rugged function consisting of consecutive valleys.

  text: "The role of gene interactions in the evolutionary process has long\r\nbeen
    controversial. Although some argue that they are not of\r\nimportance, because
    most variation is additive, others claim that\r\ntheir effect in the long term
    can be substantial. Here, we focus on\r\nthe long-term effects of genetic interactions
    under directional\r\nselection assuming no mutation or dominance, and that epistasis
    is\r\nsymmetrical overall. We ask by how much the mean of a complex\r\ntrait can
    be increased by selection and analyze two extreme\r\nregimes, in which either
    drift or selection dominate the dynamics\r\nof allele frequencies. In both scenarios,
    epistatic interactions affect\r\nthe long-term response to selection by modulating
    the additive\r\ngenetic variance. When drift dominates, we extend Robertson\r\n’\r\ns\r\n[Robertson
    A (1960)\r\nProc R Soc Lond B Biol Sci\r\n153(951):234\r\n−\r\n249]\r\nargument
    to show that, for any form of epistasis, the total response\r\nof a haploid population
    is proportional to the initial total genotypic\r\nvariance. In contrast, the total
    response of a diploid population is\r\nincreased by epistasis, for a given initial
    genotypic variance. When\r\nselection dominates, we show that the total selection
    response can\r\nonly be increased by epistasis when s\r\nome initially deleterious
    alleles\r\nbecome favored as the genetic background changes. We find a sim-\r\nple
    approximation for this effect and show that, in this regime, it is\r\nthe structure
    of the genotype - phenotype map that matters and not\r\nthe variance components
    of the population."

  text: The behaviour of gene regulatory networks (GRNs) is typically analysed using
    simulation-based statistical testing-like methods. In this paper, we demonstrate
    that we can replace this approach by a formal verification-like method that gives
    higher assurance and scalability. We focus on Wagner’s weighted GRN model with
    varying weights, which is used in evolutionary biology. In the model, weight parameters
    represent the gene interaction strength that may change due to genetic mutations.
    For a property of interest, we synthesise the constraints over the parameter space
    that represent the set of GRNs satisfying the property. We experimentally show
    that our parameter synthesis procedure computes the mutational robustness of GRNs
    –an important problem of interest in evolutionary biology– more efficiently than
    the classical simulation method. We specify the property in linear temporal logics.
    We employ symbolic bounded model checking and SMT solving to compute the space
    of GRNs that satisfy the property, which amounts to synthesizing a set of linear
    constraints on the weights.

  text: 'The theory of population genetics and evolutionary computation have been
    evolving separately for nearly 30 years. Many results have been independently
    obtained in both fields and many others are unique to its respective field. We
    aim to bridge this gap by developing a unifying framework for evolutionary processes
    that allows both evolutionary algorithms and population genetics models to be
    cast in the same formal framework. The framework we present here decomposes the
    evolutionary process into its several components in order to facilitate the identification
    of similarities between different models. In particular, we propose a classification
    of evolutionary operators based on the defining properties of the different components.
    We cast several commonly used operators from both fields into this common framework.
    Using this, we map different evolutionary and genetic algorithms to different
    evolutionary regimes and identify candidates with the most potential for the translation
    of results between the fields. This provides a unified description of evolutionary
    processes and represents a stepping stone towards new tools and results to both
    fields. '

  text: Evolutionary algorithms (EAs) form a popular optimisation paradigm inspired
    by natural evolution. In recent years the field of evolutionary computation has
    developed a rigorous analytical theory to analyse their runtime on many illustrative
    problems. Here we apply this theory to a simple model of natural evolution. In
    the Strong Selection Weak Mutation (SSWM) evolutionary regime the time between
    occurrence of new mutations is much longer than the time it takes for a new beneficial
    mutation to take over the population. In this situation, the population only contains
    copies of one genotype and evolution can be modelled as a (1+1)-type process where
    the probability of accepting a new genotype (improvements or worsenings) depends
    on the change in fitness. We present an initial runtime analysis of SSWM, quantifying
    its performance for various parameters and investigating differences to the (1+1)
    EA. We show that SSWM can have a moderate advantage over the (1+1) EA at crossing
    fitness valleys and study an example where SSWM outperforms the (1+1) EA by taking
    advantage of information on the fitness gradient.
