CoqInterval
Interval package for Coq
Keywords: Interval arithmetic - Coq
Functional Description: CoqInterval is a library for the proof assistant Coq.
It provides several tactics for proving theorems on enclosures of real-valued expressions. The proofs are performed by an interval kernel which relies on a computable formalization of floating-point arithmetic in Coq.
The Marelle team developed a formalization of rigorous polynomial approximation using Taylor models in Coq. In 2014, this library has been included in CoqInterval.
