After the hard work done on the integration of floating-point arithmetic reasoning two years ago, 2018 is the year of polymorphic SMT2 support and efficient SAT solving for Alt-Ergo. In this post, we recap the main novelties last year, and we announce the first Alt-Ergo Users’ Club meeting. An SMT2 front-end with prenex polymorphism As … What’s new for Alt-Ergo in 2018? Here is a recap!
A new release of Alt-Ergo (version 2.2.0) is available. You can get it from Alt-Ergo’s website. An OPAM package for it will be published in the next few days. The major novelty of this release is a new experimental front-end that supports the SMT-LIB 2 language, extended prenex polymorphism. This extension is implemented as a … Release of Alt-Ergo 2.2.0
A new release of Alt-Ergo (version 2.1.0) is available on Alt-Ergo’s website: https://alt-ergo.ocamlpro.com/#releases. An OPAM package for it will be published soon. In this release, we mainly improved the CDCL-based SAT solver to get performances similar to/better than the old Tableaux-like SAT. The CDCL solver is now the default Boolean reasoner. The full list of … Release of Alt-Ergo 2.1.0
We have recently released a new (public up-to-date) version of Alt-Ergo. We focus in this article on its main new feature: experimental support for models generation. This work has been done with Frédéric Lang, an intern at OCamlPro from February to July 2016. The idea behind models generation The idea behind this feature is the … Release of Alt-Ergo 1.30 with experimental support for models generation
After the public release of Alt-Ergo 0.99.1 last December, it’s time to announce a new major private version (1.00) of our SMT solver. As usual: we freely provide a JavaScript version on Alt-Ergo’s website, we provide a private access to our internal repositories for academia users and our clients. Quick Evaluation A quick comparison between … Private Release of Alt-Ergo 1.00
Recently, we worked on an online Javascript-based serverless version of the Alt-Ergo SMT solver. In what follows, we will explain the principle of this version of Alt-Ergo, show how it can be used on a realistic example and compare its performances with bytecode and native binaries of Alt-Ergo. Compilation “Try Alt-Ergo” is a Javascript-based version … Try Alt-Ergo in Your Browser
As announced in a previous post, I joined OCamlPro at the beginning of September and I started working on Alt-Ergo. Here is a report presenting the tool and the work we have done during the two last months. Alt-Ergo at a Glance Alt-Ergo is an open source automatic theorem prover based on SMT technology. It … Alt-Ergo @ OCamlPro: Two months later
