DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES COMPUTER SCIENCE COLLOQUIUM - Wednesday, June 30, 1982. Prof. J. A. George of this department will speak on "Some Ideas and Unsolved Problems in Sparse Matrix Computations." TIME: 3:30 PM ROOM: M&C 5158 ABSTRACT This talk will deal with some algorithms and computa- tional techniques that have proven to be effective in sparse matrix computation. These include dissection strategies, the minimum degree algorithm, "throw- away" techniques, and some ideas based on matrix splitting. In addition to describing the algorithms and techniques, some unsolved problems associated with them will be discussed. Coffee and refreshment will be served at 3:00 PM pri- or to the talk.
