The MRPI method improves wire length of Minimum Spanning Tree (MST) by pairwise interchanging of cells. The idea of the improvement area is introduced as an idea of searching for the cell pairs to reduce wire length of MST. Good experimental results have been observed for wire length and excution time.}, title = {Minimum Spanning Treeに基づいた配置改善手法}, year = {1995} }
