Optimal path and minimal cost

[georgesakarellos]

Hi John!

I managed to get your code to run, but it took some modifications. In the 'Example usage' I used the following code to get it to run in a new python file in the same directory:

---

from AntColonyOptimizer import AntColonyOptimizer
import numpy as np
problem = some_distance_matrix

problem = np.array(problem)
optimizer = AntColonyOptimizer(ants=1, evaporation_rate=.1, intensification=2, alpha=1, beta=1,
beta_evaporation_rate=0, choose_best=.1)

best = optimizer.fit(problem, 100)
optimizer.plot()

---

With this I managed to get a performance vs iterations graph (an odd one...) but I'm uncertain on how to get the code to display the optimal path and the minimum cost. Any advice?

Thanks,
George

Hi @georgesakarellos! What did you need to change to get it to run? Seems to run fine on my local machine.

I don't have any code to display the optimal path, although that should be saved in self.best_path, so creating one shouldn't be too hard. Minimum cost should be saved in self.best.

Note that it's been quite some time since I wrote this code, so I'm a bit rusty with it 😄. But if you have any other questions, feel free to ask!
