Abstract

Abstract—The problem of geometrical partitioning the multiple connected orthogonal polygon is considered in the given paper. The problem refers to the NP-hard class of problems because it is necessary to fulfill exhaustive search for assured finding the optimal solution. It stipulates the interest for developing efficient heuristic methods for solving the above problem. Some multiply-connected orthogonal polygon is supposed to be parted into a set of rectangles avoiding their intersecting and their crossing the polygon borders. The goal function represents certain minimization of summarized length of boundary junctions in the process of partitioning. The mathematical model of the problem is offered. The algorithm based on improving the size coefficient, characterizing the degree of rectangle elongation, has been developed. The algorithm consists of two procedures applied sequentially: the first one is for generating the primary polygon partitioning, and the second is for primary partitioning transformation taking into account the adjacent elements and the compound adjacent elements. The computing experiment has been carried out and the results are shown.
