ITP 2011

The next iteration of the interactive theorem-proving conference, ITP 2011, is in Nijmegen this year. See all the details at the official web-page.

Note the important paper submission details! (Abstracts due 13 February; full papers a week after that.)

Robin Milner has died

...Robin Milner died on Saturday 20th March, in Cambridge, just three days after the funeral of his wife, Lucy.

There may well be notices at Cambridge and Edinburgh in due course.

See the Wikipedia page for more on his career. From the ITP perspective, he is famous for his work on the influential LCF system.

Online Prover Repositories

Most, if not all, of the interactive theorem-proving systems used today are open source, meaning that their source-code is freely available. Not only can you read the source code yourself, but you can also write your own systems based on that code if you wish. In addition, some make their development repositories available for browsing. John Harrison recently announced that HOL Light now has its Subversion repository being hosted on Google Code, so I thought I’d provide links to those systems' repositories I know of.

• Coq is on Subversion, at INRIA, at svn://scm.gforge.inria.fr/svn/coq/

• HOL4 is on Subversion, at Sourceforge, at https://hol.svn.sourceforge.net/svnroot/hol/HOL

  HOL4’s repository is also available via git, at github, at git://github.com/mn200/HOL.git

• HOL Light is on Subversion, at Google Code, at http://hol-light.googlecode.com/svn/trunk/

• Isabelle is on Mercurial, at Munich, at http://isabelle.in.tum.de/repos/isabelle

Note that all of those URLs above are for use by the respective version-control systems’ initialisation and cloning commands; they will not necessarily work as targets for web-browsers.

Call for Papers for ITP 2010

There is a call for papers up now on the FLoC website. The deadline for abstracts is 15 January. So get to it!

The conference of the same name

Interactive Theorem-Proving is not just the name of this web-log, but is also the name of a conference due to happen in 2010 as part of the Federated Logic Conference (FLoC) in Edinburgh. ITP will also continue as a separate conference subsequently.

Ex nihilo

I’ve created this blog so as to give myself an OpenID. But I suppose it’s just possible I’ll become seduced by the whole interface and use it for more than just that.
