h1. COOL - The Coalgebraic Ontology Logic Reasoner

COOL is a generic reasoner for modal and hybrid logics; it can be instantiated to any modal or hybrid logic admitting an axiomatization in terms of so-called rank-1 rules or axioms. Current instantiations include multimodal K (i.e. the description logic ALC), graded modal logic (the Q in ALCQ), and coalition logic (the next-step logic of alternating temporal logic ATL). COOL currently supports global assumptions, i.e. general TBoxes, nominals, and satisfaction operators; the latter features are similar in expressivity to Boolean ABoxes. COOL implements a global caching algorithm described "here": (also available "here":

A system description of COOL (_COOL -- A Generic Satisfiability Checker For Coalgebraic Logics with Global Assumptions_, D. Gorin, D. Pattinson, L. Schröder, F. Widmann and T. Wißmann) is forthcoming at "IJCAR 2014":
