Hungarian algorithm java. I am following this guide step by step.

Hungarian algorithm java. The assignment problem takes a set of agents, a set of tasks and a cost associated with assigning each agent to each task and produces an optimal (i. I have an NxN cost matrix. Apr 26, 2025 · The Hungarian algorithm (also known as the Munkres assignment algorithm) is designed to find an optimal assignment between n agents and n tasks with a worst-case time complexity of O (n³). , least cost) assignment of agents to tasks. The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal-dual methods. So I have the costMatrix [N] [N] and 2 arrays to track covered rows and covered cols - rowCover [N], rowColumn [N] (1 means covered, 0 means uncovered) How can I cover the 0s with the minimum number of lines?
