On minimal hard classes of graphs
D. S. Malyshev Nizhegorodskiy State University, N. Novgorod, Russia
Abstract:
We consider the notions of a minimal hard class of graphs and a boundary class of graphs. We prove that there is no minimal hard classes for problem of recognition belonging to a hereditary class. We point out boundary and minimal hard classes of graphs for the list-ranking problems. These classes of graphs are the first examples of minimal hard classes and the first examples of hard boundary classes. Bibl. 9.
Keywords:
computational complexity, minimal hard class, boundary class, recognition of hereditary property, list-ranking problems.
