  text: Weak convergence of inertial iterative method for solving variational inequalities
    is the focus of this paper. The cost function is assumed to be non-Lipschitz and
    monotone. We propose a projection-type method with inertial terms and give weak
    convergence analysis under appropriate conditions. Some test results are performed
    and compared with relevant methods in the literature to show the efficiency and
    advantages given by our proposed methods.

  text: In this paper, we introduce a relaxed CQ method with alternated inertial step
    for solving split feasibility problems. We give convergence of the sequence generated
    by our method under some suitable assumptions. Some numerical implementations
    from sparse signal and image deblurring are reported to show the efficiency of
    our method.

  text: This paper aims to obtain a strong convergence result for a Douglas–Rachford
    splitting method with inertial extrapolation step for finding a zero of the sum
    of two set-valued maximal monotone operators without any further assumption of
    uniform monotonicity on any of the involved maximal monotone operators. Furthermore,
    our proposed method is easy to implement and the inertial factor in our proposed
    method is a natural choice. Our method of proof is of independent interest. Finally,
    some numerical implementations are given to confirm the theoretical analysis.

  text: The paper introduces an inertial extragradient subgradient method with self-adaptive
    step sizes for solving equilibrium problems in real Hilbert spaces. Weak convergence
    of the proposed method is obtained under the condition that the bifunction is
    pseudomonotone and Lipchitz continuous. Linear convergence is also given when
    the bifunction is strongly pseudomonotone and Lipchitz continuous. Numerical implementations
    and comparisons with other related inertial methods are given using test problems
    including a real-world application to Nash–Cournot oligopolistic electricity market
    equilibrium model.

  text: In this paper, we present two new inertial projection-type methods for solving
    multivalued variational inequality problems in finite-dimensional spaces. We establish
    the convergence of the sequence generated by these methods when the multivalued
    mapping associated with the problem is only required to be locally bounded without
    any monotonicity assumption. Furthermore, the inertial techniques that we employ
    in this paper are quite different from the ones used in most papers. Moreover,
    based on the weaker assumptions on the inertial factor in our methods, we derive
    several special cases of our methods. Finally, we present some experimental results
    to illustrate the profits that we gain by introducing the inertial extrapolation
    steps.

  text: We consider inertial iteration methods for Fermat–Weber location problem and
    primal–dual three-operator splitting in real Hilbert spaces. To do these, we first
    obtain weak convergence analysis and nonasymptotic O(1/n) convergence rate of
    the inertial Krasnoselskii–Mann iteration for fixed point of nonexpansive operators
    in infinite dimensional real Hilbert spaces under some seemingly easy to implement
    conditions on the iterative parameters. One of our contributions is that the convergence
    analysis and rate of convergence results are obtained using conditions which appear
    not complicated and restrictive as assumed in other previous related results in
    the literature. We then show that Fermat–Weber location problem and primal–dual
    three-operator splitting are special cases of fixed point problem of nonexpansive
    mapping and consequently obtain the convergence analysis of inertial iteration
    methods for Fermat–Weber location problem and primal–dual three-operator splitting
    in real Hilbert spaces. Some numerical implementations are drawn from primal–dual
    three-operator splitting to support the theoretical analysis.

  text: In this paper, we propose a new iterative method with alternated inertial
    step for solving split common null point problem in real Hilbert spaces. We obtain
    weak convergence of the proposed iterative algorithm. Furthermore, we introduce
    the notion of bounded linear regularity property for the split common null point
    problem and obtain the linear convergence property for the new algorithm under
    some mild assumptions. Finally, we provide some numerical examples to demonstrate
    the performance and efficiency of the proposed method.

  text: In this paper, we consider reflected three-operator splitting methods for
    monotone inclusion problems in real Hilbert spaces. To do this, we first obtain
    weak convergence analysis and nonasymptotic O(1/n) convergence rate of the reflected
    Krasnosel'skiĭ-Mann iteration for finding a fixed point of nonexpansive mapping
    in real Hilbert spaces under some seemingly easy to implement conditions on the
    iterative parameters. We then apply our results to three-operator splitting for
    the monotone inclusion problem and consequently obtain the corresponding convergence
    analysis. Furthermore, we derive reflected primal-dual algorithms for highly structured
    monotone inclusion problems. Some numerical implementations are drawn from splitting
    methods to support the theoretical analysis.

  text: The projection methods with vanilla inertial extrapolation step for variational
    inequalities have been of interest to many authors recently due to the improved
    convergence speed contributed by the presence of inertial extrapolation step.
    However, it is discovered that these projection methods with inertial steps lose
    the Fejér monotonicity of the iterates with respect to the solution, which is
    being enjoyed by their corresponding non-inertial projection methods for variational
    inequalities. This lack of Fejér monotonicity makes projection methods with vanilla
    inertial extrapolation step for variational inequalities not to converge faster
    than their corresponding non-inertial projection methods at times. Also, it has
    recently been proved that the projection methods with vanilla inertial extrapolation
    step may provide convergence rates that are worse than the classical projected
    gradient methods for strongly convex functions. In this paper, we introduce projection
    methods with alternated inertial extrapolation step for solving variational inequalities.
    We show that the sequence of iterates generated by our methods converges weakly
    to a solution of the variational inequality under some appropriate conditions.
    The Fejér monotonicity of even subsequence is recovered in these methods and linear
    rate of convergence is obtained. The numerical implementations of our methods
    compared with some other inertial projection methods show that our method is more
    efficient and outperforms some of these inertial projection methods.

  text: In this paper, we introduce an inertial projection-type method with different
    updating strategies for solving quasi-variational inequalities with strongly monotone
    and Lipschitz continuous operators in real Hilbert spaces. Under standard assumptions,
    we establish different strong convergence results for the proposed algorithm.
    Primary numerical experiments demonstrate the potential applicability of our scheme
    compared with some related methods in the literature.

  text: 'We consider the monotone variational inequality problem in a Hilbert space
    and describe a projection-type method with inertial terms under the following
    properties: (a) The method generates a strongly convergent iteration sequence;
    (b) The method requires, at each iteration, only one projection onto the feasible
    set and two evaluations of the operator; (c) The method is designed for variational
    inequality for which the underline operator is monotone and uniformly continuous;
    (d) The method includes an inertial term. The latter is also shown to speed up
    the convergence in our numerical results. A comparison with some related methods
    is given and indicates that the new method is promising.'

  text: The main contributions of this paper are the proposition and the convergence
    analysis of a class of inertial projection-type algorithm for solving variational
    inequality problems in real Hilbert spaces where the underline operator is monotone
    and uniformly continuous. We carry out a unified analysis of the proposed method
    under very mild assumptions. In particular, weak convergence of the generated
    sequence is established and nonasymptotic O(1 / n) rate of convergence is established,
    where n denotes the iteration counter. We also present some experimental results
    to illustrate the profits gained by introducing the inertial extrapolation steps.

  text: It is well known that many problems in image recovery, signal processing,
    and machine learning can be modeled as finding zeros of the sum of maximal monotone
    and Lipschitz continuous monotone operators. Many papers have studied forward-backward
    splitting methods for finding zeros of the sum of two monotone operators in Hilbert
    spaces. Most of the proposed splitting methods in the literature have been proposed
    for the sum of maximal monotone and inverse-strongly monotone operators in Hilbert
    spaces. In this paper, we consider splitting methods for finding zeros of the
    sum of maximal monotone operators and Lipschitz continuous monotone operators
    in Banach spaces. We obtain weak and strong convergence results for the zeros
    of the sum of maximal monotone and Lipschitz continuous monotone operators in
    Banach spaces. Many already studied problems in the literature can be considered
    as special cases of this paper.
