An efficient quasi-physical quasi-human algorithm for packing equal circles in a circular container.
Computers & Operations Research（2018）
摘要
•Propose a local BFGS algorithm to speed up the gradient descent.•Propose a new basin-hopping strategy based on “alternate tension with relaxation”.•Obtain 66 new patterns with smaller containers or n=1,⋯,320.
