Complexity of finding embeddings in a k-tree. (English) Zbl 0611.05022
A k-tree is an undirected graph that can be reduced to the k-complete graph by a sequence of removals of k-degree vertices with completely connected neighbors. A partial k-tree is a subgraph of a k-tree; \(k_ t(G)\) is the smallest k for which G is a partial k-tree.
The problem PARTIAL K-TREE is: given a graph G and an integer k, is \(k_ t(G)\leq k?\) The authors prove that PARTIAL K-TREE problem is NP-complete. For a fixed k, they present a polynomial time algorithm for that problem which, unfortunately, is of degree k.
