We want to cover the room with a minimum number of pieces and to waste a minimum amount of material. We present in this paper a synthesis of our works. We can easily see that the two criteria, the minimum… (More)

We study in this paper a cutting-covering problem, defined by us in [2] and [3], the problem of covering a rectangular support with rectangular pieces cut from a roll. We first prove that the algorithm used in [2] and [3] for the rectangular cutting-covering problem without losses is not optimal. Starting from a decomposition of a natural number in sums of… (More)

We consider a rectangular covering problem, where a rectangular support P is covered by k rectangular pieces Ci, for i=1, 2, ..., k, without gaps or overlapping. We intend to cover the support P with the k pieces in a certain order so that, at the moment of the placement of the piece Ci, the northern and western borders of this piece are completely covered.… (More)
