Title: Flows and cuts with constraints Author: Dušan Knop Department: Department of applied mathematics Supervisor: Doc. Mgr. Petr Kolman, PhD, Department of applied mathematics Abstract: In this thesis we study the problem of length bounded cuts between two vertices of a graph. In this problem the task is to find a set of edges such that after its removal the minimal distance between the two vertices is as prescribed. The work provides a basic overview of the literature on this problem and presents it in the context of other theoretical problems. It also offers some applications of length bounded cuts and flows. We describe some heuristics for data reduction. The main result of this thesis is a polynomial time algorithm in series-parallel ...
