Introduction - problem. After the liberalization problems emerged in the supply, investment and price side. An optimization algorithm is a procedure which is executed iteratively by comparing various solutions till an optimum or a satisfactory solution is found.

We give an introductory overview of the basics of Robust convex Optimization RO : a methodology aimed at immunizing optimization problems against uncertainty in the data. We saw how to solve one kind of optimization problem in the Absolute Extrema section where we found the largest and smallest value that a function would take on an interval.
