In this paper, the problem of calculating optimal layout patterns of small rectangles on a pallet is considered. We propose new heuristics which are based on the 4-block structure of layout patterns and build the mathematical model. In order to investigate the computational result of the proposed algorithms, numerical tests with randomly generated instances were carried out. By comparing, the solutions of the numerical examples show the effectiveness of this approach.
