Constraint

class flopt.constraint.Constraint(expression, _type, name=None)

Constraint Class

three type constraint, == or <=

• eq type (equal) expression == 0

• le type (less than or equal) expression <= 0

Parameters:

• expression (Expression family) – expression of constraint.

• type (ConstraintType) – Constraint type (Eq or Le)

Notes

For some types, the constraint class may not be created if the constant is placed on the left side.
