Fundamentals of Optimization and Introduction to Constraint Programming

This session will cover the fundamentals of optimization and introduce constraint programming. Optimization is the selection of a best element (with regard to some criteria) from some set of available alternatives. Constraint programming is a programming paradigm where relations between variables are stated in the form of constraints.
