Constraints

A constraint is an equality or inequality that restricts the domain of an optimization problem. CVXPY has five types of constraints: non-positive, equality or zero, positive semidefinite, second-order cone, and exponential cone. The vast majority of users will need only create constraints of the first three types. Additionally, most users need not know anything more about constraints other than how to create them. The constraint APIs do nonetheless provide methods that advanced users may find useful; for example, some of the APIs allow you to inspect dual variable values and residuals.
