A c++ demo for Hungarian algorithm (Kuhn-Munkres Algorithm) based on Apollo Hungarian Optimizer which is a implementation of Munkres’ Assignment Algorithm-Modified for Rectangular Matrices.

• Eigen (V3.3.7 is used here, other versions may also work.)

Just run the run.sh script under the directory of repository.

./run.sh

For the given cost matrix example in the demo

82.0f, 83.0f, 69.0f
77.0f, 37.0f, 49.0f
11.0f, 69.0f, 5.0f
8.0f,  9.0f,  98.0f

You will the output result like

The assignments are: 

    (1, 1)
    (2, 2)
    (3, 0)

The result means row 1 is assigned to column 1, row 2 is assigned to column 2, and row 3 is assigned to column 0.

Attention, both the indices of rows and columns of the cost matrix start at 0.
