What is the principle of the Hungarian method?
The Hungarian Method is based on the principle that if a constant is added to every element of a row and/or a column of cost matrix, the optimum solution of the resulting assignment problem is the same as the original problem and vice versa.
Which is the best way to solve the assignment problem?
Although assignment problem can be solved using either the techniques of Linear Programming or the transportation method, the assignment method is much faster and efficient. This method was developed by D. Konig, a Hungarian mathematician and is therefore known as the Hungarian method of assignment problem.
What's the Hungarian algorithm for the assignment problem?
For each row of the matrix, find the smallest element and subtract it from every element in its row. Do the same (as step 1) for all columns. Cover all zeros in the matrix using minimum number of horizontal and vertical lines. Test for Optimality: If the minimum number of covering lines is n, an optimal assignment is possible and we are finished.
Why is the Hungarian method called a cost matrix?
HUNGARIAN METHOD Although an assignment problem can be formulated as a linear programming problem, it is solved by a special method known as Hungarian Method because of its special structure. If the time of completion or the costs corresponding to every assignment is written down in a matrix form, it is referred to as a Cost matrix.
