We study probabilistic complexity classes and questions of derandomisation from a logical point of view. For each logic L we introduce a new logic BPL, bounded error probabilistic ...
We study definability of languages in arithmetic and the free monoid by bounded versions of fixed-point and transitive-closure logics. In particular we give logical characterisat...
Abstract. GridTest is a framework for testing automated theorem provers using randomly generated formulas. It can be used to run tests locally, in a single computer, or in a comput...
It is known that for temporal languages, such as firstorder LT L, reasoning about constant (time-independent) relations is almost always undecidable. This applies to temporal des...

For ontologies represented as Description Logic Tboxes, optimised DL reasoners are able to detect logical errors, but there is comparatively limited support for resolving such pro...
