Ibex 2.2.0 (message for developers)

I am pleased to announce the release 2.2.0 of Ibex!

The main change was to make a clear separation between:

  • The basic features (intervals computations, contractors, etc.)
  • Specific or advanced features (optimization, affine arithmetic, etc.).

Now, the basic features are the core of the library; Advanced features are spread across different plugins. Plugins can be installed or not, depending on user choice. They will be offered for download separately from the core.

Workshop "Constraints & Geometry"

 

The Ibex team and the MEA (French research group on set computation and interval methods) organize a workshop on constraints, intervals and geometry, to be held in Mine de Nantes on Monday 23th June.

Talks will be 20-30 minutes long, a lot of time (10-20 minutes) is kept on purpose for questions and discussions.

Talk at JFPC'14

Gilles Trombettoni and Gilles Chabert will give a talk at JFPC'14 in Angers (June 11th at 9:00). The talk will be about contractor programming, inner inflators and application to robust parameter estimation and global optimization.
