The classic patch choice model considers only one forager. The time interval of the rolling average is set by the user and varies from 2-100. The cost of acquiring food is computed as a rolling average of search costs / encounters over some time interval. MOVING: According to the patch choice model, a forager will continue to forage in a patch until the cost of acquiring food drops to the cost of moving to a new patch. Optionally, exhausted cells can regrow using a random function set by the user. REGROWTH: When the food is harvested, the cell's food value goes to zero. Processing the food can optionally also cost the forager (set by the user). Each cell moved costs the forager energy units (set by the user).ДЇORAGING: The forager gains energy () by harvesting and consuming the food in each cell he/she encounters that has food. They begin to move in random directions a distance set by the user. Each cell in the eco-patch (i.e., a NetLogo 'patch') has a food value (e.g., edible plants), set by the user ( in energy units or eu's).ДЇORAGERS: One or more foragers ( selected by the user) are placed randomly in the eco-patches and given 100 energy units (eu's) to start with. SETUP: The world is divided into 9 eco-patches, each with their own ID number. This is an agent-based simulation of the classic 'patch choice model' of optimal foraging theory.
