A Correct Algorithm for Identifying Independent Variable Sets in Reactive Systems (opens in new tab)

Recent work has proposed algorithms for decomposing reactive synthesis specifications into simpler and independent subspecifications. Motivated by the DecomposeContract algorithm introduced by Antonio Iannopollo, we revisit this approach and provide a mathematical account of the notion of independence on which it is based. The central idea in this setting is to identify independence among system-controlled variables in linear temporal logic ...
