Abstract
It has been shown recently that the traveling salesman (TS) problem on Halin graphs can be solved by a polynomial-time algorithm. The purpose of this paper is to discuss two problems which result from this special case of the TS problem. One of the problems is a special case of the set-partitioning ( SP ) problem in which a set family consists of the vertex sets of “interior faces” of a plane tree. The other problem is to cover the interior faces of a plane graph by a set of vertices which are face-independent.
