This year on August 3 Donald Knuth will give an invited talk during CP-2022 at Haifa, Israel. Rather than giving a canned lecture, he much prefers to let the audience choose the topics, and for all questions to be kept a secret from him until the lecture is actually in progress. (He believes that people often learn more from answers that are spontaneously fumbled than from responses that are carefully preplanned.) Questions related to constraints will naturally be quite welcome, but questions on any subject whatsoever will not be ducked! He’ll try to answer them all as best he can, without spending a great deal of time on any one topic, unless there is special interest to go into more depth. If you wish to ask a question, please send it by e-mail before July 31. Link
