Note on: An improved algorithm for the packing of unequal circles within a larger containing circle

摘要

This note proposed an improved version of the algorithm proposed by Wang et al. [Wang, H. Q., Huang, W. Q., Zhang, Q., & Xu, D. M. (2002). An improved algorithm for the packing of unequal circles within a larger containing circle. European Journal of Operational Research, 141, 339-347] for solving the disk packing problem with equilibrium constraints. An efficient strategy of accelerating the search process is introduced in the gradient method to shorten the execution time. A number of computational results are presented, showing the effectiveness of the proposed method.
