2 Ant Fitness Assessment

The fitness for this problem is measured as the number of pellets missed out of the total on the trail. The ant is typically given a total of 600 time steps[*] to collect food pellets, where each terminal takes one time step to execute. Each candidate program is re-evaluated, without re-initialising the `ant', until the all the food has been collected or the maximum number of time steps is reached.
