When to choose arbitrarily for assignment in Hungarian?
If for a row and a column, there are two or more zeros and one cannot be chosen by inspection, choose the cell arbitrarily for assignment. The above process may be continued until every zero cell is either assigned or crossed (X). Step 4
What are the steps in the Hungarian method?
Steps in Hungarian Method. 1. Identify the minimum element in each row and subtract it from every element of that row. 2. Identify the minimum element in each column and subtract it from every element of that column.
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.
How is the Hungarian method used for assignment problems?
Hungarian Method is an efficient method for solving assignment problems. This method is based on the following principle: If a constant is added to, or subtracted from, every element of a row and/or a column of the given cost matrix of an assignment problem, the resulting assignment problem has the same optimal solution as the original problem.
