Here you can adjust all settings for the simulated annealing algorithm. There are two sections in the SA settings tab:
When an criterion is checked then this will be taken into account when evaluating a solution. The number after the criterion indicates the weighing factor. Please note that it is the proportion between the different weighting factors that is important and not the number itself. Weighing factors range from 1 to 100 (disabling the criterion will set the weighing factor to zero).
Start temperature factor
The start temperature will be multiplied with this factor. With a higher start temperature more swaps will be allowed.
Cooling rate
Determines how fast the temperature will drop. The temperature is multiplied with the cooling rate after every annealing cycle. A higher cooling rate should allow better solutions to be found since more swaps will be made.
Trails per temperature
Determines the maximum number of trails each annealing cycle.
Improvements per temperature
When this number of improvements is reached the annealing cyclus is broken. This value should always be lower than the trails per temperature value.
Maximal iterations
The maximum number of annealing cycles.
Number of restarts
The number of times the algorithm is completely restarted. The best solution will be choosen from the list of solutions produced by each cycle. This is to avoid local optima.
