Solving an one-dimensional cutting stock problem by simulated annealing and tabu search

Jahromi, Meghdad HMA; Tavakkoli-Moghaddam, Reza; Makui, … - In: Journal of industrial engineering international 8 (2012), pp. 1-8

A cutting stock problem is one of the main and classical problems in operations research that is modeled as LP problem. Because of its NP-hard nature, finding an optimal solution in reasonable time is extremely difficult and at least non-economical. In this paper, two meta-heuristic algorithms,...
