Course objectives
Course provides information about constraint programming, about problem modeling using constraints generally as well as practically in programming language, about general propagating algorithms and about main search algorithms for constraint satisfaction problems.
Learning outcomes
The graduate will understand how to apply a declarative approach for problem solving with the help of constraint programming.
The graduate will understand which algorithms are used for the implementation of the constraint programming approach to be able to propose a proper declarative model and proper search procedures. To achieve that graduates will learn various constraint propagation algorithms and search methods.
The graduate will be able to implement a solution to the problem using constraint programming. The graduate will be able to program using Optimization Programming Language (OPL) from IBM CPLEX CP Optimizer.
Syllabus
  • Constraint satisfaction problem. Introduction to problem modeling.
  • Algorithms and consistency: arc, path. Methods for non-binary constraints: k-consistency, general arc, and bounds consistency, global constraints. Directional versions, the width of the constraint graph, and polynomial problems.
  • Tree search: backtracking, look ahead, look back, incomplete algorithms. Local search.
  • Optimization and over-constrained problems: frameworks and algorithms.
  • Problem modeling and real-life applications. Programming with programming language OPL in IBM ILOG CP Optimizer.

Teaching methods
The course has a form of a lecture with a seminar taking two hours per two weeks at the computer laboratory. Lecture is mainly oriented on presentations of algorithms and their practical application for solving of problems in the area of constraint programming. Solved problems are often realized using modifications of existing code. Seminaries concern namely practical realization of OPL programs in IBM ILOG CP Optimizer. Seminaries include homeworks which solutions together with solutions of examples solved during seminaries are available at the course web site.
Assessment methods
There is the following expected evaluation given as a sum of points for homeworks, final written exam, and bonus points for activities at lectures: A more than 90, B 89-80, C 79-70, D 69-60, E 59-50.
It is possible to get up to 80 points for the final written exam. The exam also includes the following types of questions: an overview of some part, comparisons of methods or definitions, algorithms, definitions, examples (about 25 points corresponds to the evaluation of the constraint model for a given problem(s)).
It is obligatory to get more than 40 out of 80 points. There are two homeworks during a semester. It is possible to get points up to 10 points per homework. Each student is required to obtain 8 points at least from the total point of 20 points.
Also, each student can get 1 bonus point for activity in each lecture (e.g., student response to several easy questions and/or student questions to clarify some part of the lecture; student response to one harder question), i.e., it is possible to about 12 bonus points for activity base on the number of lectures.
Taking seminaries is obligatory. Absence at more than one seminar requires successful completion of additional examples corresponding to the number of absent hours. A high number of missed seminaries does not allow completion of the course.
