ContinuousLinearInequalityConstraint

class baybe.constraints.continuous.ContinuousLinearInequalityConstraint

Bases: ContinuousConstraint

Class for continuous inequality constraints.

The constraint is defined as sum_i[ x_i * c_i ] >= rhs, where x_i are the parameter names from parameters and c_i are the entries of coefficients. If you want to implement a constraint of the form <=, multiply rhs and coefficients by -1. The constraint is typically fulfilled up to a small numerical tolerance.

The class has no real content as it only serves the purpose of distinguishing the constraints.
