Synopsis:

Students get knowledge of efficient algorithms for text pattern matching. They learn to use so called succinct data structures that are efficient in both access time and memory complexity. They will be able to use the knowledge in design of applications that utilize pattern matching.

Requirements:

Knowledge of basic data structures, fundamentals of computer programming, and theory of finite automata.

Syllabus of lectures:

1. Introduction, basic definitions, border array.

2. Text full index: Suffix array.

3. Text full index: Suffix tree, LCP construction.

4. Text full index: Factor, suffix automata, on-line construction.

5. Exact pattern matching algorithms.

6. FFT in pattern matching.

7. Succinct data structure: rank & select.

8. Succinct data structure: wavelet tree.

9. FM-Index.

10. Dictionary representation, spell checking.

11. Approximate pattern matching.

12. (2) Pattern matching in bioinformatics.

Syllabus of tutorials:

1. Basic definitions.

2. Text full index

3. Exact pattern matching algorithms.

4. FFT in pattern matching.

5. Succinct data structure

6. FM-Index, approximate pattern matching.

Study Objective:

The pattern matching is a key task in most applications. Its importance is increasing with enlargement of the mass of information collected. Efficient algorithms and data structures for pattern matching are therefore crucial in information processing, but also in other fields like security (e.g., intrusion detection, virus scans). This module provides an extensive overview of such algorithms and data structures.
