After that, simplest means this sub-problem being solved doesn’t depend on others being solved. Once you solved every sub-problem, connect the dots. Connecting all your “sub-solutions” will give you the solution to the original problem. Congratulations! Webbas in this case the dual problem can be used for solving the original (primal) problem. In order to arrive at such results, we have to introduce the notion of saddle points.

Sketch derivation of dual form The Representer Theorem states that the solution w can always be written as a linear combination of the training data: w = XN j=1 Webbrelationship to the original, primal, problem. 4.1 Basic Duality The study of duality is very important in LP. Knowledge of duality allows one to develop increased insight into LP solution interpretation. Also, when solving the dual of any problem, one simultaneously solves the primal. Thus, duality is an alternative way of solving LP problems.
