Stigmergy Pathfinding: Digital Pheromone Swarm

A robot swarm finds the shortest route from nest to goal with no map and no communication: each robot deposits a decaying digital pheromone marker as it moves, and later robots probabilistically favor stronger trails, so short paths self-reinforce faster than they decay while poor ones fade away.

Watch a decentralized robot swarm converge on the shortest route between a nest and a goal purely through indirect environmental signaling — no robot ever communicates directly or holds a map. Tune the pheromone evaporation rate to see the trade-off between trails that never form and trails that mislead, then relocate the obstacle mid-run to watch the swarm adaptively re-converge.

A decentralized robot swarm finds the shortest route from nest to goal purely through indirect environmental signaling: each robot deposits a decaying digital pheromone trail as it moves and later robots probabilistically favor stronger trails, so short paths self-reinforce faster than they decay while long detours fade — no robot ever holds a map or talks to another directly. Tune the decay rate and relocate the obstacle mid-run to watch the swarm adaptively re-converge.
