Is there other method better than Hungarian Method for solving an assignment problem?

The Hungarian Method is widely regarded as one of the most efficient algorithms for solving assignment problems, especially for small to medium-sized problems. However, depending on the size, structure, and specific requirements of the problem, there are other methods or variations that could be more suitable:


1. Auction Algorithm: This is a decentralized approach for solving assignment problems, particularly useful for very large-scale problems. It tends to be more flexible in handling real-time adjustments and distributed systems.

2. Branch and Bound Method: This method is useful for assignment problems with additional constraints, such as integer requirements. It explores all possible assignments by systematically branching and pruning, aiming to find the optimal solution. It can be more efficient than the Hungarian Method in cases where constraints need more detailed handling.

3. Linear Programming (LP): For larger or more complex assignment problems, especially when the problem involves fractional or continuous variables, formulating the assignment as a Linear Programming (LP) problem can be more efficient. Solvers like the Simplex Method or interior-point algorithms can handle large-scale LP assignment problems effectively.

4. Genetic Algorithms: For assignment problems with non-linear or highly complex objectives, heuristic approaches like Genetic Algorithms may outperform traditional methods. They are especially useful when the problem size is too large or difficult to model precisely.


While these methods have their advantages, the Hungarian Method is typically the most efficient and straightforward for standard assignment problems where minimizing cost or maximizing profit is the primary goal. However, for specific scenarios like very large-scale, complex, or constrained problems, other methods may offer better performance.

The Hungarian Method is highly efficient and widely used, but depending on the problem structure, other methods like the Auction Algorithm or Genetic Algorithms might offer better performance for solving certain assignment problems.

 Here are some other methods for solving assignment problems:

  1. Enumeration Method: This method involves systematically enumerating all possible assignments and calculating the total cost for each assignment. While this method guarantees finding the optimal solution, it can be computationally inefficient for large problems.
  2. Simplex Method: The simplex method, which is commonly used for linear programming problems, can also be applied to solve assignment problems. However, it may not be as efficient as the Hungarian Method for this specific problem1.
  3. Transportation Method: The transportation method, which is used to solve transportation problems, can also be adapted to solve assignment problems. However, the degeneracy problem of the solution makes the transportation method computationally inefficient for assignment problems.
