Automatically generating a rule set implementation is disclosed. A set of rules is accessed. For each non-const rule in the set of rules, one or more implication directed acyclic graphs (DAGs) are constructed. The non-const rule directly causes at least one external output or at least one external action. The one or more implication DAGs specify rule conditions, including one or more observable rule conditions. Implication DAGs that are constructed for the set of rules are compiled to obtain a compiled result that is configured to evaluate rule conditions associated with the set of rules and determine one or more actions when at least one of the rule conditions evaluates to true. The compiled result is output.
