The dependency pairs method is one of the most powerful technique for proving termination of rewriting and it is currently central in most automatic termination provers. Recently,...
The Tower of Hanoi problem is generalized by placing pegs on the vertices of a given directed graph G with two distinguished vertices, S and D, and allowing moves only along arcs o...
One of the previous articles in this column was devoted to the zero-one laws for a number of logics playing prominent role in finite model theory: first-order logic FO, the extens...
We describe a framework of algebraic structures in the proof assistant Coq. We have developed this framework as part of the FTA project in Nijmegen, in which a constructive proof ...

Certified software consists of a machine-executable program plus a formal machine-checkable proof that the software is free of bugs with respect to a claim of dependability. The c...
