Paths/cycles of prescribed parity in planar digraphs.

ABSTRACT

In this paper we enlighten the structure of paths of prescribed parity in planar digraphs and we present a polynomial time algorithm for solving the following problem: given a planar digraph G and a face F of G such that G - F has no even cycle, find a path of prescribed parity between two specified vertices of F. The same algorithm can be recursively applied to provide a polynomial time procedure for finding even cycles in G - F (if any).
