In this paper we consider the well known p-median problem. We introduce a new large neighborhood based on ideas of S.Lin and B.W. Kernighan for the graph partition problem. We study the behavior of… (More)

Consideration was given to the p-median problem for minimum in the integer formulation which is known to be NP-hard. Variants of the algorithms of ant system and simulated annealing were proposed for… (More)

Recently much attention is given to the approximate methods of solution of combinatorial optimization problems. Special interest is conserned with the algorithms which are constructed on analogies… (More)
