Summary: Testing whether intermediate strategy-age inertia creates a cooperation window in hypergraph public-goods games near threshold synergy.

Higher-order public-goods games capture group interactions that cannot be reduced to pairwise links, while behavioral inertia can slow switching between strategies. This experiment asks whether those two ingredients combine to produce a middle regime where cooperation persists better than it does with either weak or very strong inertia.

The simulation runs public-goods dynamics on random hypergraphs, varies the switching inertia associated with strategy age, and compares outcomes across hyperedge sizes near the cooperation threshold. The target is an interior cooperation window rather than a monotone benefit of added persistence.

That matters because memory effects are usually studied in simpler network settings. The experiment tests whether higher-order group structure changes how inertia stabilizes cooperative behavior.

Method: Repeated stochastic public-goods-game simulations on random hypergraphs with sweeps over strategy-age inertia and hyperedge size.

What is measured: Late-time cooperation level, dependence on inertia strength, hyperedge-size effects, threshold-synergy response, and support for an interior cooperation window.
