Given an undirected graph G = (V; E), an edge cost c(e) ΒΏ 0 for each edge e β E, a vertex prize p(v) ΒΏ 0 for each vertex v β V , and an edge budget B. The BUDGET PRIZE COLLECTING TREE PROBLEM is to ΓΏnd a subtree T = (V ; E ) that maximizes vβV p(v), subject to eβE c(e) 6 B. We present a (4 + )-appro
Given a simple polygon P with n vertices and a starting point s on its boundary, the watchman route problem asks for a shortest route in P through s such that each point in the interior of the polygon can be seen from at least one point along the route. In this paper, we present a simple, linear-tim
## Abstract Given an undirected graph with edge costs and vertex prizes, the aim of the Prize Collecting Traveling Salesman Problem (PCTSP) is to find a simple cycle minimizing the total edge cost while collecting at least a minimum amount of prizes. In this article, we present a branchβandβcut alg
