The hungarian algorithm
WebThe Hungarian algorithm proposed by Kuhn (Citation 1955) is a popular optimal assignment method and a combinatorial optimization algorithm that solves assignment problems in polynomial time. Optimal assignment using the Hungarian algorithm can meet the needs of various application scenarios, such as time-optimal and cost-optimal. ... The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal–dual methods. It was developed and published in 1955 by Harold Kuhn, who gave the name "Hungarian method" because the algorithm was largely … See more Example In this simple example, there are three workers: Alice, Bob and Dora.
