Summary: Testing whether intermediate stripe-correlated mobility disorder best extends coexistence in a spatial rock-paper-scissors system.

Spatial rock-paper-scissors models are widely used to study coexistence, invasion fronts, and environmental heterogeneity. This experiment asks whether mobility disorder arranged in stripes creates a corridor effect that prolongs coexistence more effectively than either uncorrelated disorder or nearly deterministic stripe channels.

The GPU simulation varies the strength and geometry of stripe-correlated mobility disorder and compares those runs against IID and strongly ordered limits. The working idea is that intermediate stripe structure can open transport corridors without locking the entire system into rigid invasion pathways.

That makes the project a geometry-of-disorder study inside a familiar ecological game. The goal is to identify whether finite-width anisotropic corridors produce a genuinely nonmonotone coexistence response.

Method: Large batched GPU simulations of a spatial rock-paper-scissors lattice with stripe-correlated mobility disorder of varying strength.

What is measured: Coexistence time, dependence on stripe correlation, comparison with IID and strongly ordered disorder, and evidence for a nonmonotone coexistence peak.
