Uncertainty is an inherent aspect of the open-pit mine production scheduling problem (MPSP); however, little is reported in the literature about solution methods for the stochastic versions of the problem. In this paper, two variants of a variable neighbourhood descent algorithm are proposed for...

This paper presents a metaheuristic solution approach based on Tabu search for the open-pit mine production scheduling problem with metal uncertainty. To search the feasible domain more extensively, two different diversification strategies are used to generate several initial solutions to be...

The judge assignment problem consists in finding an assignment satisfying the competition rules (hard constraints) and meeting, as much as possible, the competition organizers objectives (soft constraints). In this paper, various specific real-world constraints found in organizing academic...
