| Abstract(in English) | The subject of this paper is the problem of extracting a planar spanning subgraph in a Terminal-Vertex graph model of a circuit. It is known to be NP-hard, and some heuristic algorithms have been proposed. Among them it is known that heuristic algorithms based on changing graph representation of nets give sharp solutions. In this paper, we propose a heuristic one that takes separation pairs as well as cutpoints into consideration in changing graph representation of nets, and compare its performance through computing experiments. |
