We propose to build an automated reasoning system for first-order logic (FOL) by translating reasoning problems to a fragment of FOL called coherent logic (CL) and then solving t...

We consider positive rules in which the conclusion may contain existentially quantified variables, which makes reasoning tasks (such as Deduction) undecidable. These rules have t...
