If you want to optimize the problem, you can consider using lingo to solve it. Grammar is not difficult, just look at an example. If the problem is complicated, it will take a long time, at least half an hour, and some will take a night, because it is iterative. You can also use MATLAB to solve algorithms, such as simulated annealing algorithm, ant colony algorithm, particle swarm optimization algorithm and so on. , there are ready-made programs.
