An Efficient Strategy of Shape Assignment for Block Division
This paper presents the strategies of bestfit Bottom-Left by Right first (BL-Rf) and Bottom-Left by Top first (BL-Tf) (BL-Rf/BL-Tf) for block division selection. The block solution inspires from Space Allocation Problems (SAPs) and Packing Problems (PPs), however the huge number of possible solutions the heuristic with guided strategies required for the satisfied results. The mathematical expression was formulated to represent this problem. The independent strategy by BL-Rf or BL-Tf has inconsistent result and led to fail to promote optimal solution. Therefore, BL-Rf/BL-Tf attempts to improve the result performance. The strategies applied in GA, the generated numbers of optimal solutions were stated for the purpose of analysis. The BL-Rf/BL-Tf promotes more solutions number than the independent strategies and indicates that result quality and time efficiency are better.
