Synthesis of open reactive systems from scenario-based specifications

Research output: Contribution to journalArticlepeer-review


We propose here Live Sequence Charts with a new, game-based semantics to model interactions between the system and its environment. For constructing programs automatically, we give an algorithm to synthesize either a strategy for the system ensuring that the specification is respected, or, if the specification is unimplementable, a strategy for the environment forcing the system to fail. We introduce the concept of mercifulness, a desirable property of the synthesized program. We give a polynomial time algorithm for synthesizing merciful winning strategies.
