Abstract

Computer-aided synthesis represents an emerging paradigm in design automation with many practical applications. The two main approaches to synthesis can be characterised as search-based and inductive techniques. The former use a procedure for generating candidate solutions followed by a verification procedure, and typically cannot guarantee the non-existence or optimality of a solution. The latter leverage an expensive decision procedure that directly constructs the desired solution or proves its non-existence. This project will develop a new methodology that uniquely combines the two approaches within the framework of syntax-guided synthesis. It will focus on systems embracing uncertainty, stochasticity, or approximate computation, which all require quantitative reasoning. The proposed synthesis methods will be tailored to design automation in practically relevant engineering and biological applications. We believe that the combined approach will significantly improve the capabilities of synthesis methods and pave the way towards an automated correct-by-construction design process.
