  Abstract: The approach Why3 takes to interfacing with a wide variety of interactive#R##N#and automatic theorem provers works well: it is designed to overcome#R##N#limitations on what can be proved by a system which relies on a single#R##N#tightly-integrated solver. In common with other systems, however, the degree#R##N#to which proof obligations (or “goals”) are proved depends as much on#R##N#the SMT solver as the properties of the goal itself. In this work, we present a#R##N#method to use syntactic analysis to characterise goals and predict the most#R##N#appropriate solver via machine-learning techniques.#R##N#Combining solvers in this way - a portfolio-solving approach - maximises#R##N#the number of goals which can be proved. The driver-based architecture of#R##N#Why3 presents a unique opportunity to use a portfolio of SMT solvers for#R##N#software verification. The intelligent scheduling of solvers minimises the#R##N#time it takes to prove these goals by avoiding solvers which return Timeout#R##N#and Unknown responses. We assess the suitability of a number of machinelearning#R##N#algorithms for this scheduling task.#R##N#The performance of our tool Where4 is evaluated on a dataset of proof#R##N#obligations. We compare Where4 to a range of SMT solvers and theoretical#R##N#scheduling strategies. We find that Where4 can out-perform individual#R##N#solvers by proving a greater number of goals in a shorter average time.#R##N#Furthermore, Where4 can integrate into a Why3 user’s normal workflow -#R##N#simplifying and automating the non-expert use of SMT solvers for software#R##N#verification.
