Now we assign job 3 to worker B as it has minimum cost from list of unassigned jobs. Finally, job 1 gets assigned to worker C as it has minimum cost among unassigned jobs and job 4 gets assigned to worker C as it is only Job left. Reference : www.

Let there be N workers and N jobs. Any worker can be assigned to perform any job, incurring some cost that may vary depending on the work-job assignment. It is required to perform all jobs by assigning exactly one worker to each job and exactly one job to each agent in such a way that the total cost of the assignment is minimized. Solution 1: Brute Force We generate n! possible job assignments and for each such assignment, we compute its total cost and return the less expensive assignment. Since the solution is a permutation of the n jobs, its complexity is O n!
Solution 2: Hungarian Algorithm The optimal assignment can be found using the Hungarian algorithm. We can perform depth-first search on state space tree and but successive moves can take us away from the goal rather than bringing closer. The search of state space tree follows leftmost path from the root regardless of initial state. An answer node may never be found in this approach. We can also perform a Breadth-first search on state space tree. But no matter what the initial state is, the algorithm attempts the same sequence of moves like DFS. the selection rule does not give any preference to a node that has a very good chance of getting the search to an answer node quickly.
It is similar to BFS-like search but with one major optimization. Instead of following FIFO order, we choose a live node with least cost. We may not get optimal solution by following node with least promising cost, but it will provide very good chance of getting the search to an answer node quickly. Since Job 2 is assigned to worker A marked in green , cost becomes 2 and Job 2 and worker A becomes unavailable marked in red. Now we assign job 3 to worker B as it has minimum cost from list of unassigned jobs. Finally, job 1 gets assigned to worker C as it has minimum cost among unassigned jobs and job 4 gets assigned to worker C as it is only Job left.
Below diagram shows complete search space diagram showing optimal solution path in green. Reference : www. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. This article is attributed to GeeksforGeeks. Let us explore all approaches for this problem. There are two approaches to calculate the cost function: For each worker, we choose job with minimum cost from list of unassigned jobs take minimum entry from each row. For each job, we choose a worker with lowest cost for that job from list of unassigned workers take minimum entry from each column. In this article, the first approach is followed. using namespace std;. struct Node. int pathCost;.
