Description: 标准的指派问题是一类特殊的整数规划问题，又是特殊的0-1规划问题和特殊的运输问题。1955年W. W. Kuhn利用匈牙利数学家D. Konig关于矩阵中独立零元素的定理, 提出了解指派问题的一种算法, 习惯上称之为匈牙利解法。-The standard assignment problem is a special class of integer programming problems, is 0-1 programming problems and transport problems. 1955 WW Kuhn Hungarian mathematician D. Konig independent zero elements in the matrix of the theorem, the understanding of the assignment problem an algorithm, used to be called the Hungarian Method.
