2019/05/10

Compatibility release for recent ghc version (ghc-8.6.5).
Automated Amortized Resource Analysis for Term Rewrite Systems
2017/12/01

TcT now supports amortised resource analysis of term rewrite systems (currently only avaialable at the development branch).
TcT version 3.0 released
2015/10/16

TcT version 3.0 was released. It is a complete reimplementation of version 2.0.1, which is open to arbitrary complexity problems and allows seamless integration of 3rd party solvers.
TcT won a Kurt Gödel medal
2014/07/21

In 2014, the first "FLoC Olympic Games" have been conducted during the Vienna Summer of Logic. During the games, several automatic tools competed in 14 different competitions about complexity, determinacy, satisfiablity, termination, etc. TcT competed in the termination competition and won the prize for the most powerful tool in complexity analysis of term rewrite systems.
TcT version 2.0.1 released
2013/08/06

TcT version 2.0.1 has been released. This minor release comes with updated documentation, minor bugfixes, and a more consistent naming of techniques in Tct.Instances.
TcT version 2.0 released
2013/03/19

TcT version 2.0 has been released. Besides bug-fixes and a wealth of minor improvements, notably this release adds to version 1.9:
Web Interface Updated
2013/03/01

Our web interface has been polished, it features new examples, the competition strategy of 2012 and a dedicated strategy for our RaML collection.
Complexity Competition 2012
2013/02/02

TcT participated in all four complexity categories of the complexity competition 2012. TcT won the runtime complexity category. It is the only tool participating in the innermost derivational complexity category, and the only open source tool capable of proving innermost runtime complexity. TcT could signifficantly increase its power for innermost runtime complexity, and was placed closely after AProVE (closed source).
Web Interface
2012/05/10

TcT now features an easy to use web interface.
Resource aware ML
2012/05/10

We have translated the Resource aware ML testbed to term rewrite systems. The resulting set of TRSs can be downloaded from here.
TcT version 1.9 released
2012/01/01

This version presents the last milestone before version 2.0. Besides various bugfixes, most notably following new features are added:
