Partial k-tree

In graph theory, a partial k-tree is a type of graph, defined either as a subgraph of a k-tree or as a graph with treewidth at most k. Many NP-hard…

The treewidth of graph G is the minimum integer k to make a subgraph of a k-tree by G. It can be also defined in terms of…

We describe a general approach to obtain polynomial-time algorithms over partial k-trees for graph problems in which the vertex…

Many combinatorial problems can be efficiently solved for partial k-trees (graphs of treewidth bounded by k). The edge-coloring…
