How it works

Breadth-first search explores board positions one move at a time, guaranteeing the shortest solution when every move has equal cost.

Example

Treat each slide as an edge between states and skip positions already visited. The first route to the exit is optimal.

Key point

Breadth-first search explores board positions one move at a time, guaranteeing the shortest solution when every move has equal cost.
