Bioinformatic Algorithms, UNIL 2020
Instructors: Prof. Christophe Dessimoz (CD) & Prof. David Gfeller
(DG)
Assistants: Dr. Alex Warwick Vesztrocy and Simon Eggenschwiler
15h lecture, 15h practical, 10h personal work (3 ECTS)
The course aims at improving the student’s programming skills by gaining a
deep understanding of some of the key algorithms in bioinformatics, with a
special emphasis on sequence and graph algorithms. Students will learn
widely applicable concepts, such as asymptotic time complexity, binary
search, suffix trees, dynamic programming, hashing, hidden Markov models,
and neuronal networks.
Practicals and home assignments are essential parts of the course. The
language of the course is Python, though the concepts covered in the course
are applicable to all computer languages.
Assessment:
20 min oral examination
Prerequisites:
The course assumes familiarity with basic programming concepts (variable
and function declaration, arrays, for-loops, conditional statements, etc.).
Algorithms are introduced from a practical angle so the mathematical
formalism is kept at a minimum.
