In this video, useful concepts were discussed related to non-linear programming. The idea was to deliver an introduction to non-linear problems and non-linear solvers before starting to use them. Linear vs. Non-linear; Convexity vs. Concavity; Continuity vs. Discontinuity; and Smoothness vs. Non-smoothness were discussed. Also, how the two solver engines – GRG and Evolutionary work is also explained.
