Sparse Matrix Computations
Algorithmique des matrices creuses
Semester: Fall, 2010
Schedule: Friday, 10h15--12h15
Classroom: Salle B1
Instructors: Jean-Yves L'Excellent and Bora Uçar
Sparse matrix computations, mostly the solution of sparse linear systems of equations, are at the core of many scientific computing applications.
Often, discrete mathematical algorithms and techniques, mostly from graph theory, are used to achieve efficiency in these kind of computations. In this course, we will explore the interplay between these two seemingly distant domains.
Prerequisites: There is no specific background requirement for the course. The necessary material will be introduced throughout the semester. A little maturity in mathematical reasoning, working knowledge of basic linear algebra, and exposure to algorithm design can help understand the course contents (and many other things).
Evaluation: The students are expected to study research articles related to the contents of the course, write a report, and do an oral presentation.
Texts: We will not be following a particular text book. We will use course notes and research and survey articles throughout the semester.
