Web18.2 Algorithm for Assignment Problem (Hungarian Method) Step 1 Subtract the minimum of each row of the effectiveness matrix, from all the elements of the respective rows (Row reduced matrix). Step 2 Further modify the resulting matrix by subtracting the minimum element of each column from all the elements of the respective columns. WebI then realized that Egerv´ary’s paper gave a computationally trivial method for reducing the general assignment problem to a 0-1 problem. Thus, by putting the two ideas together, the Hungarian Method was born. I tested …
WebThe Hungarian method is a combinatorial optimization algorithm which was developed and published by Harold Kuhn in 1955. This method was originally invented for the best assignment of a set of persons to a set of jobs. It is a special case of the transportation problem. The algorithm finds an optimal assignment for a given “n x n” cost matrix.
