The final solution can be read in the file output/<simulation-name>/expansion/out.json, in the field solution.

For each iteration:

1. The investment combination that has been evaluated,
2. The operational, investment and overall costs,
3. The current lower and upper bounds (no upper bound for the Benders by batch),
4. The absolute and relative gap,
5. The resolution time for the subproblems and the master problem.

There is also information on the iteration number which has led to the best solution.

!!! warning The last iteration of the optimization is not necessarily the best solution.

The file out.json also gives the parameters that are used by the optimization algorithm (some of them are defined by the user in settings.ini).

You can also find the best and last iteration of the algorithm in the last_iteration.json.
