We present BioMASS. a new model to implement a spatially explicit environment that supports constant-time sensory (neighborhood search) and locomotion functions for situated multiagent systems (MAS). In contrast. the spatial models currently provided by agent-based modeling and computer simulation (ABMS) platforms have computational costs that grow quadratically with perception range ... https://www.mabelandfoxs.shop/product-category/pop-up-tunnel/
