Learning Outcomes

Upon successful completion of the course, the student will be able to:

  • Know/state mathematical theory (concepts, theorems, proofs) which related to the course in question.
  • Recognize the mathematical formulas related to the theory and to describe the solution methods (e.g. Method M)
  • Distinguish different cases of linear problems programming and explain their use in relation to the given mathematical problem. (e.g. Binary theory, the transference problem.)
  • Compute basic elements of the theory (e.g. solution via the Simplex technique).
  • Understand, distinguish, and resolve the different cases of the issues that concern integer programming (Branch and bound, the partition problem, the minimum set overlap problem, dynamic programming, the knapsack problem (generalized knapsack)
  • Fix problems with the local search method (e.g. Neighborhood Structure, methods neighborhood search, the street vendor problem, graph partitioning.)
  • Explain and solve problems using Heuristic algorithms (Techniques performance evaluation, reachability ratio, the nodal overlap problem (vertex covering), maximum independent subset, upper and lower bounds, empirical evaluation of heuristics).
  • Combine mathematical theory with problems of an economic nature that fall within in the course and to successfully proceed to exemplify them.
