Map 1 Map 2
In the graph titles you will notice five arguments between brackets.
The argument, which is tested on the graph, is not written between the brackets.
The other ones are written as follow:
Number of ants, error free steps, number of pheromones,
put pheromone rate, pick pheromone rate, threshold.

" "
Conclusion of the ant graph:
The relationship between the number of ants and the number of ants is hyperbolic,
i.e. the number of steps is invertially proportionnal to the number of ants.

" "
Conclusion of the error free step graph:
For "Map 1", we can notice that the number of needed steps is hazardous.
But, for "Map 2", we can observe that the ants should not make too many mistakes,
that means: the scarcer the errors, the better the score.
Somewhere over 50 error free steps the number of rounds will increase,
because there is not enough hazard to get the optimal way.

" "
Conclusion of the put pheromone rate graph:
In "Map1",because of the long way between the nest and the food,
we can notice that it is better to put lower percentages of pheromones
in order to draw longer ways back to the nest.
In "Map2", the results are not clear enough to be interpretated,
but it is still more efficient to use a low percentage of pheromones.

" "
Conclusion of the pick pheromone rate graph:
In both cases,
it is better to take an important amount of pheromones off the ground,
in order to prevent the ants from walking in circles,
and to allow them to find other ways too.
