WHAT IS IT?

The agent-based computational algorithm used by turtle agent is based on Wilensky [1] and gives to this the next improvements:
(i) the algorithm has a variable number of searching directions in comparison with the Wilensky algorithm that has only four directions; thus the number of searching direction can vary from 4 to 360.
(ii) the algorithm has two regimes: one is deterministic and uses the searching directions and the other is random and is used only if the first regime fails to find the resources that surrounds the agent.
HOW IT WORKS

Press Setup in order to Setup computer simulation. Then Press Go for start of computer simulation. The simulation will stop when all the resources are harvested.

HOW TO USE IT

You can change the number of agents from 1 to 10, the Directions parameter from 4 to 360 the random seed from -2 to 2 and Scarcity parameter from 10 to 100.

THINGS TO NOTICE

You will see that if you increase the number of agents the period of harvesting will be shorten. In addition if you increase the number of directions you obtain the same result. If you modify the RandomSeed then you obtain different results.

THINGS TO TRY

Run the five experiments from BehaviorSpace option of Tools menu.
