Module grid 

2D grid spaces with integer coordinates.

Two variants are provided:

• Grid2D - multi-occupancy: each cell can hold any number of agents.
• Grid2DSingle - single-occupancy: each cell holds at most one agent.

Both support periodic (toroidal) and non-periodic (bounded) boundaries. Neighbor queries use Chebyshev distance (8-connected / square neighborhood).

Mirrors Julia Agents.jl GridSpace and GridSpaceSingle.
