Summary: Testing whether intermediate temporal persistence of blocked sites improves jammed coverage in 2D dimer adsorption compared with rapidly refreshed or nearly frozen disorder.

Random sequential adsorption is strongly affected by the geometry of the substrate, but dynamic disorder introduces an additional timing question. This experiment asks whether blocked-site patterns that persist for an intermediate time create better adsorption corridors than either constantly refreshed disorder or nearly frozen obstacles.

The script simulates 2D dimer adsorption on lattices with time-dependent blocked masks and compares final jammed states across persistence levels. The underlying hypothesis is that moderate memory preserves useful pathways long enough to help filling, without permanently sealing off the voids that still need to be reached.

That makes the project a nonmonotonic substrate-memory study. The aim is to identify whether there is a genuine persistence window where temporal disorder improves both coverage and residual void structure.

Method: Repeated 2D dimer random-sequential-adsorption simulations with blocked-site masks whose temporal persistence is systematically varied.

What is measured: Jammed coverage, void fragmentation, dependence on obstacle persistence, and support for an interior optimum.
