The tree decomposition of graphs is a fundamental algorithmic tool. It has been shown that difficult problems, such as some NP-complete ones, can be solved efficiently over classes of graphs of ...

The heuristic computes a tree decomposition of a given graph by using the clique graph operator. First the maximal cliques of the given graph are computed which in general can take exponential time ...

Given a graph in sage structure or an adjacency list of the graph, returns the modular decomposition tree (cotree), if the input graph is cograph. Functions included: Cograph_recognition: Contains 3 ...

It is well-known that dynamic programming algorithms can utilize tree decompositions to provide a way to solve some \emph{NP}-hard problems on graphs where the complexity is polynomial in the number ...

Given a cyclic ordering of external particles and an n-point tree Feynman graph T, the tree-graph integral F_T is defined in such a way that F_T has only the poles relevant to T, that there is a ...
