Bistable system

A rare event in a bistable system. Left: time-dependent probability density for a bistable system consisting of two competitive species. Right: a single realization of the system is simulated and plotted on top of the density. Note the scale of the time for this problem, explaining the term 'rare event'; the expected time for the system to switch its configuration is relatively long.

(Plot info: each axis tick is 25 molecules and the contour levels have been chosen by Matlab)
