Abstract : Alt-Ergo is an SMT solver jointly developed by Université Paris-Sud and the OCamlPro company. The first version was released in 2006. Since then, its architecture has been continuously adapted for proving formulas generated by software development frameworks. As type systems with polymorphism arise naturally is such platforms, the design of Alt-Ergo has been guided (and constrained) by a native-and non SMT-LIB compliant-input language for a polymorphic first-order logic. In this paper, we present the last version of Alt-Ergo, its architecture and main features. The main recent work is a support for a conservative polymorphic extension of the SMT-LIB 2 standard. We measure Alt-Ergo's performances with this new frontend on a set of benchmarks coming from the deductive program verification systems Frama-C, SPARK 2014, Why3 and Atelier-B, as well as from the SMT-LIB benchmarks library.
