In cutting stock problems, after an optimal (minimal stock usage)
cutting plan has been devised, one might want to further reduce the
operational costs by minimizing the number of setups. A setup
operation occurs each time a different cutting pattern begins to be
produced. The related optimization problem is known as the Pattern
Minimization Problem, and it is particularly hard to solve exactly.
In this paper, we present different techniques to strengthen a
formulation proposed in the literature....
