 Abstract
Generally, the optimal solution of assignment problem can be obtained by Hungarian algorithm of two-sided optimization with time complexity . This paper suggests one-sided optimal assignment and swap optimization algorithm with time complexity can be achieve the goal of two-sided optimization. This algorithm selects the minimum cost for each row, and reassigns over-assigned to under-assigned cell. Next, that verifies the existence of swap optimization candidates, and swap optimizes with . For 27 experimental data, the swap-optimization performs only 22% of data, and 78% of data can be get the two-sided optimal result through one-sided optimal result. Also, that can be improves on the solution of best known solution for partial problems.
