DOI: 10.1007/s13675-019-00113-9
Abstract: In the two-dimensional guillotine cutting-stock problem, the objective is to minimize the number of large plates used to cut a list of small rectangles. We consider a variant of this problem, which arises in glass… read more here.

DOI: 10.1080/00207543.2022.2070882
Abstract: We address three variants of the two-dimensional cutting stock problem in which the guillotine cutting of large objects produces a set of demanded items. The characteristics of the variants are the rectangular shape of the… read more here.

DOI: 10.1134/s1990478920010184
Abstract: We consider the well-known one-dimensional cutting stock problem in order to find some integer instances with the minimal length L of a stock material for which the round-up property is not satisfied. The difference between… read more here.
