Currently, the system uses the rewrite engine of the computer algebra system {\em Mathematica} for building and combining a number of automatic/interactive provers (high-order predicate-logic, induction for lists/tuples and natural numbers, etc.) in natural deduction style and in natural language presentation. These provers can be used for defining and proving properties of mathematical models and algorithms, while a specially provided ``computing engine'' can execute directly the logical description of these algorithms. =howpublished= CADE 98 (Computer Aided Deduction), Lindau, Germany, July 1998, Workshop on Integrating Computation and Deduction =sponsor= Austrian Science Foundation (FWF), project FO-1302 (SFB). =keywords= automated reasoning
