He K, et al. Sci China Inf Sci April 2018 Vol. 61 048104: 2 problem, and each maximal unoccupied rectangular space is called an action space for a packing pattern. By an innovative idea of approximating each circle as a square, He et al.[6] proposed an action space based global optimization (ASGO) algorithm for the problem that packs unequal circles into a square container. For some given patterns, ASGO utilized the limited-memory Broyden-Fletcher-Goldfarb-Shanno (LBFGS) algorithm [7] for continuous optimization to reach the local minimums. Then, each circular item is approximated as a square item, and an actionspace-based basin-hopping strategy is adapted to find the larger unoccupied spaces as candidate places to replace some of the most overlapping items in order to jump from a local minimum. In this article, PAS-PCI approximates each circular item as a square item by setting its width as [1+(1//
