Coq proof assistant

Compare

  Analyzed about 1 month ago

Coq is a formal proof management system: a proof done with Coq is mechanically checked by the machine. In particular, Coq allows: * to define functions or predicates, * to state mathematical theorems and software specifications, * to develop interactively formal proofs of these theorems, * to ... [More] check these proofs by a relatively small certification "kernel". [Less]
