Efficient enumeration algorithms for minimal graph completions and deletions |
This thesis is about graph theory and more specifically enumeration algorithms for subgraphs or supergraphs. The problem we consider is the following: given a graph G and a graph property P, can we find an efficient algorithm generating exactly once all the inclusion-wise maximal (induced or not) subgraphs of G that satisfy the property P? We are interested as well in inclusion-wise minimal supergraphs of G - called minimal completions of G - verifying P.
Efficient algorithms, running with polynomial delay in polynomial space, are obtained for some of these problems when P describes the classes of split graphs, cographs, threshold graphs and chordal graphs.
