“…So, some heuristic methods are generally proposed to solve it. For the circular packing problem in a rectangular container, the solving algorithms include the heuristic tabu search algorithm [1], the heuristic algorithm based on bounded enumeration strategy for evaluating corner placement [2], et al For the problem of packing circles into a larger circular container, some authors have developed various heuristic algorithms to generate approximate solutions, including the quasi-physical quasi-human algorithm [3][4][5], the complete quasi-physical algorithm [6], the Pruned-Enriched Rosenbluth Method (PERM) [7], the dynamic adaptive local search algorithm [8], the simulated annealing (SA) [9] and its improved algorithms [10,11], the beam search algorithm [12] and the adaptive beam search algorithm [13], the energy landscape paving (ELP) method [14,15], the global optimization algorithm based on the quasi-physical method [16], and others.…”
