"""Application file that runs all algorithms for the RailNL case that were
created by Team Gekke Hackers.

Algorithms:

0. Hillclimber > works for Holland map and National map
1. Hillclimber with simulated annealing > works for Holland map and National map
2. Greedy > due to performance only works for Holland map
