Graph of all Bistable

Each colored square represents a bistable reaction scheme. Click on any square to go to the selected reaction.
The color represents the propensity for this reaction to be bistable, that is, the fraction cases that are bistable, when assigned random parameters. The pale blue lines connect simpler models (below) to bistable models which can be formed by adding a single reaction to the simpler model.
