释义

König-Egervary theorem


The König-Egervary theorem states that in a finite matrix of 0’s and 1’s, the maximum numbers of 1’s such that no two are in a line, equals the minimum number of lines which collectively contain all the 1’s. Here line means row or column.

Take this matrix, for example,

[100001100001010001010001101110]

Here the max and min numbers (always equal) are 4.
