wmpy.core.inequality.Inequality

class Inequality(expr, variables, env)

Bases: object

Internal class for inequalities in the canonical form:

P {<,<=} 0

where P is a degree 1 polynomial.

strict

boolean flag, true when the inequality is <

mgr

pysmt formula manager

polynomial

the Polynomial P

Default constructor.

Parameters:

• expr (FNode) – the inequality in pysmt format

• variables (Collection[FNode]) – the continuous integration domain

• env (Environment) – the pysmt environment
