In locust-inspired models, what triggers the global decision for the swarm to move from a space?

Answer

When a sufficient number of agents ($N_{ ext{trigger}}$) reach an excited state due to high local density.

The global decision in locust models is triggered when the internal state variable causes enough agents to enter an 'excited state' based on frequent local interactions indicating high density.
