KKT conditions
(4.4 hours to learn)
Summary
The Karush-Kuhn-Tucker (KKT) conditions are a set of optimality conditions for optimization problems in terms of the optimization variables and Lagrange multipliers.
Context
This concept has the prerequisites:
- convex optimization (The KKT conditions characterize optimal solutions to convex optimization problems.)
- Langrange duality (The KKT conditions involve both the primal and dual variables.)
- gradient (The optimality conditions are given in terms of gradients.)
