When to use Hungarian method for assignment problem?
Whenever the pay off matrix of any assignment problem is not a square matrix i.e. no. of rows not equal to number of columns the problem is called unbalanced assignment problem. Hungarian method of solving such problem is as follows: 1. Insert row or column with all values zero such that pay off matrix become square matrix. 2.
When to cross out zeros in the Hungarian algorithm?
For every zero that becomes assigned, cross out (X) all other zeros in the same row and the same column. If for a row and a column, there are two or more zeros and one cannot be chosen by inspection, then you are at liberty to choose the cell arbitrarily for assignment.
