Termination Competition

Annual International Termination Competition

During the 90's a number of new, powerful termination methods was developed. Thus, at the the beginning of the millennium many research groups started to develop tools for fully-automated termination analysis.

After a tool demonstration at the 2003 Workshop on Termination in Valencia, the community decided to install an annual termination competition to spur the development of tools and new termination techniques.

Currently, the competition features the following categories:

• termination of string and term rewriting
• certified termination of string and term rewriting (see Workshops on Certified Termination)
• termination of logic programs
• termination of functional programs
• complexity of term rewriting

Planned extensions:

• termination of java bytecode programs

The Termination Problems Data Base collects all the problems used in the competitions.

So far, the following competitions have taken place:

• Termination Competition 2004
• Termination Competition 2005
• Termination Competition 2006
• Termination Competition 2007

At the 2007 Workshop on Termination in Paris it was decided to discontinue the annual competitions in favour of an ongoing competition.

• Termination Competition 2008

Discussion is open and primarily happens on the termtools mailing list. Decisions will be made by votes among the Termination Competition Steering Committee.
