Experiment 1 tests the generalization capabilities of the genomes based on the relative direction the target is

TRAINING
Training is done in a maze where the robot is in the center, and the targets are positioned around the agent. Each
run has a single target sampled. The targets all are positioned 6 meters from the robot's initial position.
TESTING
Testing is done similar as was the case for training, however, in this scenario only 20 targets are sampled (where
there were 36 for training). Only 4 of these 20 sampled target positions overlap with the training set.

Experiment 6 is another 'simplified' simulation in which the agents are trained on a harder environment than they

TRAINING
During training, new targets are spawned based on the agent's initial position. Each target will lay between 2 and
10 meters from the agent and will always be positioned inside of the maze.
TESTING
Testing is done on 18 predefined targets position in a relative angle from the agent of k*20° and a distance of
either 4, 6, or 8 meters (sequential alternating).
