Instructor: Shaojie Zhang
Lectures: Tu/Th 4:30-5:45 pm ENGR 0383
Office hours: Tu/Th 2:30-3:30 pm HEC 311
Syllabus: The course will concentrate on computer science aspects of computational molecular biology and will emphasize the recent advances and open problems in the area.
The computational techniques will include algorithms, graph theory, combinatorics, machine learning, etc. Many important bioinformatics topics will be used as examples to illustrate how the formulation and solution of a computer science problem can help to answer a biological question.
This course is designed for computer science graduate students. No biology knowledge is required.
Graduate students with either biology or physical/computer science backgrounds who have taken a fundamental bioinformatics course are also welcome to take this course.
Preliminary topics to be covered: 1. Introduction to algorithms 2. Exact string matching, Data structure: Suffix tree 3. Suffix tree: applications 4. Mismatch tree and the motif finding problem 5. Breaking problems down: dynamic programming 6. Combinatorial search: intractable problems 7. Integer programming; Reductions 8. Graph algorithms: trees 9. Haplotyping via perfect phylogeny 10. Comparing trees 11. De Bruijn graph; Eulerian graphs 12. Minimum Spanning trees; Shortest paths 13. Matching problems; Network flow 14. Breakpoint graph 15. Set cover and set packing 16. Graph-based clustering 17. Heuristic algorithms
