Optimal Path Cover Problem on Block Graphs and Bipartite Permutation Graphs
نویسندگان
چکیده
The optimal path cover problem is to find a minimum number of vertex disjoint paths which together cover all the vertices of the graph. Finding an optimal path cover for an arbitrary graph is known to be NP-complete [3]. However, polynornial-time algorithms exist for trees [4], cacti [4] and for interval graphs [9]. The solution presented in [2] For circular-arc graphs is known to be wrong. In this paper, we

Linear structure of bipartite permutation graphs and the longest path problem
The class of bipartite permutation graphs is the intersection of two well known graph classes: bipartite graphs and permutation graphs. A complete bipartite decomposition of a bipartite permutation graph is proposed in this note. The decomposition gives a linear structure of bipartite permutation graphs, and it can be obtained in O(n) time, where n is the number of vertices. As an application o...
متن کاملBipartite permutation graphs
Bipartite graphs and permutation graphs are two well known subfamilies of the perfect graphs. Neither of these families is contained in the other, and their intersection is nonempty. This paper shows that graphs which are both bipartite and permutation graphs have good algorithmic properties. These graphs can be recognized in linear time, and several problems which are NP-complete or of unknown...
متن کاملOn the linear structure and clique-width of bipartite permutation graphs
Bipartite permutation graphs have several nice characterizations in terms of vertex ordering. Besides, as AT-free graphs, they have a linear structure in the sense that any connected bipartite permutation graph has a dominating path. In the present paper, we elaborate the linear structure of bipartite permutation graphs by showing that any connected graph in the class can be stretched into a "p...
متن کاملInduced matchings in asteroidal triple-free graphs
An induced matching M of a graph G is a set of pairwise nonadjacent edges such that no two edges of M are joined by an edge in G. The problem of /nding a maximum induced matching is known to be NP-hard even for bipartite graphs of maximum degree four. In this paper, we study the maximum induced matching problem on classes of graphs related to AT-free graphs. We /rst de/ne a wider class of graph...
متن کاملMinimal Universal Bipartite Graphs
A graph U is (induced)-universal for a class of graphs X if every member of X is contained in U as an induced subgraph. We study the problem of finding a universal graph with minimum number of vertices for various classes of bipartite graphs: exponential classes of bipartite (and general) graphs, bipartite chain graphs, bipartite permutation graphs, and general bipartite graphs. For exponential...
