Synopsis:

The students will gain knowledge and understanding necessary deployment of combinatorial heuristics at a professional level. They will be able not only to select and implement but also to apply and evaluate heuristics for practical problems.

Requirements:

Basic notions: algorithm, computational complexity, asymptotic complexity. Formal languages. Basic graph theory. Random variable. Boolean logic. Branch and bound algorithm. Basic dynamic programming. Practical programming in any imperative language.

Syllabus of lectures:

1. Combinatorial problems and algorithms, course introduction.

2. Experimental evaluation of algorithms.

3. The classes P and NP. Complementary problems. Polynomial hierarchy.

4. The classes NP-complete, NP-hard and NPI.

5. The classes PO and NPO. Classes of approximative problems. Deterministic approximation algorithms.

6. State space, search space, motion in state space, local heuristics, branch and bound.

7. Randomization and randomized algorithms. Experimental deployment of parametrized heuristics.

8. Simulated annealing.

9. Simulated evolution I: taxonomy, genetic algorithms.

11. Simulated evolution III: building blocks theory, competent GA, fast messy GA. Stochastic optimization: models and applications. Bayesian optimization.

12. Global methods, taxonomy of decomposition-based methods. Exact and heuristic global methods, the Davis-Putnam procedure seen as a global method.

13. Constraint Satisfaction Problem

Syllabus of tutorials:

1. Introduction, Satisfiability Problem (SAT), Knapsack Problem.

11. Simulated evolution: deployment and evaluation I

12. Simulated evolution: deployment and evaluation I

13. Backup test term, evaluation.

Study Objective:

Many practical tasks are computationally infeasible. The course is about fast algorithms for such problems, both exact and heuristic. Heuristic algorithms tend to be simple to program, but difficult to configure and deploy. Their successful application requires a deeper understanding of their operation and complexity theory. A series of individual works guides the student from simple techniques to solutions of practically significant problems.
