This module contains an algorithm to solve the Linear Assignment Problem. It has the same functionality as linear_assignment.pyx, but is much slower as it is vectorized in numpy rather than cython
- class LinearAssignment(costs, epsilon=1e-06)
This class finds the solution to the Linear Assignment Problem. It finds a minimum cost matching between two sets, given a cost matrix.
This class is an implementation of the LAPJV algorithm described in: R. Jonker, A. Volgenant. A Shortest Augmenting Path Algorithm for Dense and Sparse Linear Assignment Problems. Computing 38, 325-340 (1987)
costs – The cost matrix of the problem. cost[i,j] should be the cost of matching x[i] to y[j]. The cost matrix may be rectangular
epsilon – Tolerance for determining if solution vector is < 0
- property min_cost
Returns the cost of the best assignment
