## Abstract We show that for an interval graph given in the form of a family of intervals, a maximum independent set, a minimum covering by disjoint completely connected sets or cliques, and a maximum clique can all be found in __O__(__n__ log __n__) time [__O__(__n__) time if the endpoints of the
## Abstract We introduce a simple new technique which allows us to solve several problems that can be formulated as seeking a suitable orientation of a given undirected graph. In particular, we use this technique to recognize and transitively orient comparability graphs, to recognize and represent
## Abstract The __p__βcenter problem is to locate __p__ facilities on a network so as to minimize the largest distance from a demand point to its nearest facility. The __p__βmedian problem is to locate __p__ facilities on a network so as to minimize the average distance from a demand point to its c
We present a simple optimal algorithm for the problem of finding maximum independent sets of circular-arc graphs. Given an intersection model S of a circular-arc graph G , our algorithm computes a maximum independent set of G in O ( n ) space and O ( n ) or O(n log n ) time, depending on whether the
