Efficient algorithms with performance guarantees for some problems of finding several discrete disjoint subgraphs in complete weighted graph. (English) Zbl 1338.05263
Summary: Some hard-to solve combinatorial problems of finding several disjoint discrete structures in complete weighted graph are considered. Efficient algorithms with performance guarantees are constructed for the Euclidean $$m$$-Peripatetic Salesman Problem, $$m$$-Weighted Clique Problem and $$m$$-Layer Planar three-index Assignment Problem.
