| Abstract(in English) | Sequence-pair, which is a representation method of rectangular block packing, is extended to represent a rectilinear polygonal block packing. Consequently, it includes some infeasible sequence-pairs. which do not correspond to any packing. The infeasible sequence-pairs thus make the search for the best packing difficult and also require a long time for it. This paper proposes following three methods: (1) making each vertex of constraint graphs to correspond to not a rectangle but a block so as to reduce the time taken for obtaining the packing based on a sequence-pair; (2) generating an adjacent sequence-pair without producing a certain infeasible one: (3) and determining infeasible sequence-pairs independent on the size of the block within O(n log n) time. Experiments show the effectiveness of these proposed methods implemented by Simulated Annealing. |
