A survey of heuristics for the weighted matching problem. (English) Zbl 0532.90090
This survey paper reviews results on heuristics for two weighted matching problems: matchings where the vertices are points in the plane and weights are Euclidean distances, and the assignment problem. Exact algorithms for these problems have $$0(n^ 3)$$ time bound, where n is the number of points. Several fast heuristics, typically with 0(n) and $$0(n^ 2)$$ time bounds, are described in detail and results are given for worst-case ratio bounds, absolute bounds, and expected bounds. Applications to practical problems and some mathematical complements are also included.
