VARIABLE NEIGHBORHOOD SEARCH FOR ORDER BATCHING IN A WAREHOUSE [PDF]
Asia-Pacific Journal of Operational Research, 2009 In this paper we address the problem of batching orders in a warehouse, with the objective of minimizing the total travel time. Order batching is an NP-hard optimization problem that is very difficult to solve exactly in practice. Thus, most implemented solutions are based on elementary heuristic methods that perform a relatively limited exploration ...

New variable neighborhood search method for minimum sum coloring problem on simple graphs [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2018 The minimum sum coloring problem (MSCP) is to find a legal vertex coloring for G using colors represented by natural numbers (1,2, . . .) such that the total sum of the colors assigned to the vertices is minimized. The aim of this paper is to present the

MPI Parallelization of Variable Neighborhood Search
Electronic Notes in Discrete Mathematics, 2012 Abstract We analyze five parallelization strategies for the Variable Neighborhood Search (VNS) meta–heuristic. They are based on the asynchronous cooperative execution of several threads on different processors. Some of them are adapted from the recent literature, while the others are the newly proposed. We test parallelization on various levels, and
