Crowd Your Way Out of a Paper Bag
summary
Simulations show simple agent rules producing realistic crowd effects: a one‑lane queue produces ghost jam stop‑and‑go waves; a two‑lane hack causes risky lane swaps and near‑crashes; a grid CA with von Neumann neighborhood uses a static floor field to bias motion toward exits; adding tables with local temptation creates blocking and inefficient eating. Code is prototyped in C++ (slides and repo linked) and demos prove removing empty tables or using a genetic algorithm to place food speeds evacuation. Results are quantitative enough to optimize layouts.
