[{"publication_status":"published","abstract":[{"lang":"eng","text":"Let S be a set of n closed intervals on the x-axis. A ranking assigns to each interval, s, a distinct rank, p(s)∊ [1, 2,…,n]. We say that s can see t if p(s)<p(t) and there is a point p∊s∩t so that p∉u for all u with p(s)<p(u)<p(t). It is shown that a ranking can be found in time O(n log n) such that each interval sees at most three other intervals. It is also shown that a ranking that minimizes the average number of endpoints visible from an interval can be computed in time O(n 5/2). The results have applications to intersection problems for intervals, as well as to channel routing problems which arise in layouts of VLSI circuits."}],"quality_controlled":"1","volume":34,"page":"129 - 144","extern":"1","date_published":"1990-01-01T00:00:00Z","publisher":"Taylor & Francis","date_created":"2018-12-11T12:06:46Z","publist_id":"2051","citation":{"apa":"Edelsbrunner, H., Overmars, M., Welzl, E., Hartman, I., &#38; Feldman, J.
