Inequality

New in version 1.1.0.

class nexus.Inequality(*args)

Abstract class for inequality constraints. Do not use this class directly. An inequality must be derived from this class in Python the following way.

# definition of the derived class
class InequalityDefinedInPython(nx.Inequality):
    def __init__(self, id="user id"):
        super().__init__(id)

    # implementation of the actual inequalities
    # must return a bool
    # The function must be able to return True values, otherwise the optimization will fail.
    def Function(self):
        ineq1 = a > b

        ineq2 = b + c > 1

        ...

        return ineq1 * ineq2 * ...

Parameters:

id (string) – User identifier.

id

User identifier.

Type:

string
