"The purpose of the CrabSim model is to investigate the foraging behavior of sand-bubbler crabs in light of optimal foraging theory. The model is based on Zimmer-Faust’s 1987 foraging study of Scopimera inflata, which incorporated empirical observations (including experimental components) and mathematical modeling of observed and optimal crab foraging behavior (Zimmer-Faust, 1987). The goal of the model’s initial phase of development (CrabSim 1.0) is to evaluate this IBM implementation of a central-place forager against the predictions made by the original model, identify correspondences and discrepancies, and investigate situations where the IBM implementation may provide an advantage."
