Euclidean distance cost based multi robot task allocation with MILP(Mixed Intger Linear Programming) modeling.
gurobi_minsum.py is 2D decision variable version.
gurobi_minsum_2.py and gurobi_minmax.py are 3D decision variable version.
Since the naive implementation of subtour elimination constraints requires too much cost(memory, computation time), lazy constraint callback version for each algorithm is implemented.
