Enhanced Adjacent Extreme-point Search and Tabu Search for the Minimum Concave-cost Uncapacitated Transshipment Problem
针对凹成本无容量转运网络优化问题，改进了邻接极值点搜索算法，并将其嵌入禁忌搜索框架，在部分实例中显著提升了求解质量，同时提供了另一种计算更高效的方案。
Practicable methods for optimising concave-cast, uncapacitated transshipment networks are non exact. In this paper, one such effective method, that of adjacent extreme point search, is further developed to enhance its overall computational efficiency. The enhanced search algorithm is then imbedded in a tabu search scheme which proved capable of finding better solutions, by a wide margin in some instances. Another tabu search scheme, somewhat inferior in terms of solution quality but computationally more efficient, is also developed to provide an alternative solution vehicle for larger networks. Results of extensive computational testing are included.
