The twenty-second Householder Symposium on Numerical Linear Algebra is this week, June 8 - June 13, 2025 at Cornell. My talk on Wednesday had the provocative title "A Million-Dollar Matrix". A PDF of the slides available at link_1. The talk covers posts in the Cleve's Corner blog last fall. link_2, link_3, link_4.... 더 읽어보기 >>

A friend is investigating the use of generative AI in his classes. I asked two different popular chatbots to write MATLAB programs for a mathematically nontrivial problem. Both chatbots understood my query and both wrote plausible MATLAB programs, but one of the programs was not correct. My recommendation for coursework: carefully read and test programs produced by generative AI and repair any incorrect ones.... 더 읽어보기 >>
The Closest Pair of Points problem is a standard topic in an algorithms course today, but when I taught such a course fifty years ago, the algorithm was not yet known.... 더 읽어보기 >>

(I have a guest blogger today. Ron Jones worked with me in 1985 for his Ph. D. from the University of New Mexico. He retired recently after nearly 40 years at Sandia National Labs in Albuquerque and now has a chance to return to the problem he studied in his thesis. -- CBM)... 더 읽어보기 >>
When I tackle a Wordle puzzle, I like to make all the key decisions myself. My three assistants set up puzzles and suggest words when I ask for help, but I guide the actual solution. My assistants also make it possible for me to play Wordle anywhere, anytime, even when my laptop is in airplane mode. I don't need the New York Times or access to the Web.... 더 읽어보기 >>
