Fully Observable Non-deterministic Planning as Assumption-Based Reactive Synthesis [PDF]

, 2018
We contribute to recent efforts in relating two approaches to automatic synthesis, namely, automated planning and discrete reactive synthesis. First, we develop a declarative characterization of the standard “fairness” assumption on environments in non ...
