"From Correctness to High Quality"

( MPI-SWS talk in Kooperation mit dem Fachbereich Informatik)

In the synthesis problem, we are given a specification over input and output signals, and we synthesize a system that realizes the specification: with every sequence of input signals, the system associates a sequence of output signals so that the generated computation satisfies the specification. The above classical formulation of the problem is Boolean. The talk surveys recent efforts to automatically synthesize reactive systems that are not only correct, but also of high quality. Indeed, designers would be willing to give up manual design only after being convinced that the automatic procedure that replaces it generates systems of comparable quality. We distinguish between behavioral quality, which refers to the way the specification is satisfied, and costs, which refer to resources that the system consumes. We argue that both are crucial for synthesis to become appealing in practice.
