Title: Algorithms on interval filament graphs
Authors: Fanica Gavril
PDFCS-2007-03.pdf
Abstract: We describe polynomial time algorithms to find holes and antiholes of a given parity, and minimum dominating holes, in interval filament graphs, circular-arc filament graphs and subtree filament graphs, implying polynomial time algorithms to test for perfectness. Also, we describe polynomial time algorithms to find minimum coverings by cliques for their subfamilies of perfect graphs. The class of interval filament graphs, introduced by Gavril, contains the classes of cocomparability, polygon-circle and chordal graphs.
