## Detailed Description

The convergence certificate for the BHRZ03 widening operator.

Convergence certificates are used to instantiate the BHZ03 framework so as to define widening operators for the finite powerset domain.

Note:
  Each convergence certificate has to be used together with a compatible widening operator. In particular, BHRZ03_Certificate can certify the convergence of both the BHRZ03 and the H79 widenings.

## Member Function Documentation

int Parma_Polyhedra_Library::BHRZ03_Certificate::compare | ( | const BHRZ03_Certificate & | y | ) | const

The comparison function for certificates.

Returns:
  , or depending on whether `*this` is smaller than, equal to, or greater than `y`, respectively.

Compares `*this` with `y`, using a total ordering which is a refinement of the limited growth ordering relation for the BHRZ03 widening.
