An assignment problem is a particular case of transportation problem where the objective is to assign a number of resources to an equal number of activities so as to minimize total cost or maximize total profit of allocation.

The assignment problem is one of the fundamental combinatorial optimization problems in the branch of optimization or operations research in mathematics. It consists of finding a maximum weight matching (or minimum weight perfect matching) in a weighted bipartite graph .

In this OR-Wiki entry we’re going to explain the Hungarian method with 3 examples. In the first example you’ll find the optimal solution after a few steps with the help of the reduced matrix.

A new algorithm for the generalized assignment problem is presented that employs both column generation and branch-and-bound to obtain optimal integer solutions to a set partitioning formulation of the problem.

Abstract- Amongst the humongous possible known solution to address the maximization assignment problem (MAP), herewith we posit a new method. To start with assignment matrix is defined, this matrix is then reduced so as to form a matrix with each row to contain one
