ECTS credit allocation (and other scores): 6.00 Basic information on ECTS credits allocation principles:
  • the annual hourly workload of the student’s work required to achieve the expected learning outcomes for a given stage is 1500-1800h, corresponding to 60 ECTS;
  • the student’s weekly hourly workload is 45 h;
  • 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes;
  • weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS;
  • work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load.

Algorithms and data structures 1000-213bASD

Short description:

The lecture covers basic algorithms on texts (strings), as well as related algorithmic techniques and data structures (suffix trees, subword graphs). The classical problems are string-matching, repetitions, symmetries and compression. Also some problems will be discussed related to computational biology and textual generation of two-dimensional fractals. The course covers also some algorithmics on compressed texts, the complexity status of basic problems can unexpectably

change to NP or PSPACE completeness in the compressed setting. A relatively short part of the course is devoted to combinatorics on words.

Learning outcomes:

Student has basic knowledge of basic problems and techniques in algorithmics on teksts, in particular:

1. He can prove correctness and can construct efficient algorithms

2. Knows main combinatorail propertis of words

3. has basic knowledge about basic data structures related to texts

4. knows basic alfgorithms, in particular algoritgms of Knutha-Morris-Pratt, Boyer-Moore and Karkainen Sanders

5. can design fast algorithms related to texts, sequences and trees

Capabitities(K_U07):

The student can understand algorithmic problem in this area and can, by himself, propose effcient algorithmic solution

Potrafi samodzielnie wyspecyfikować problem algorytmiczny z tej dzidziny, dokonać jego analizy i zaproponować wydajne rozwiązanie.

Social skills (K_K01-K_K09):

The student can search for related informations and judge their suitability.

Assessment methods and assessment criteria:

The final grade is a result of a written exam. Most active students during the semester will be exempted from the exam.

In the case of completing the course by a doctoral student, the student will read a selected recent research article and a chat with a lecturer about the article will be a part of the exam.
