Boundary classes for the list-ranking problems in subclasses of forests
Abstract:
All boundary classes are found for the graph list-ranking problems (vertex and edge variants) relative to the class of forests. It allows to determine the complexity status of these problems for any hereditary class defined by a finite set of forbidden subgraphs under the class of forests.
