A list of rules or rule base, which is a specific type. The rule set can either be translated into a model such as markov chains or differential equations, or be treated using tools that directly work on the rule set in place of a translated model, as the latter is typically much bigger. Rulebased modeling is an effective way of handling the explosive combinatorics of biological networks. By taming the combinatorial explosion, and exposing the causal structures and key kinetic junctures in a model, agent and rulebased representations hold promise for making modelling more powerful, more perspicuous, and of appeal to a wider audience.
