Subset of instances used in the paper "A heuristic for the cutting stock problem in the steel industry: a real application"

This paper, which is currently under review, proposes a heuristic algorithm for a cutting stock problem in the steel industry. This problem occurs in a Spanish company and the proposed algorithm is currently in production after being validated on real company data and compared with an exact mixed integer linear optimization model (MILO).

The dataset presented here includes twenty instances used in the paper (the rest cannot be presented for confidentiality reasons). For each instance, the order and coil characteristics are provided, as well as the compatibility between these two. Finally, for each instance, the solution of the model, the heuristic algorithm, and the hybrid algorithm are provided.
