It&#x27;s not useful as a reference, but it is full of delight – though only if you actually do the problems. Many of them are chains of inquiry that build on each other and culminate in some result that gives you so much intuition about whatever it was they were dealing with.<p>If you&#x27;re in the Toronto region, I actually run a reading group for these books: <a href="http:&#x2F;&#x2F;www.meetup.com&#x2F;Knuth-Reading-Group-Art-of-Computer-Programming&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.meetup.com&#x2F;Knuth-Reading-Group-Art-of-Computer-Pr...</a>. We get together about once a month and go through the problems together. Just last night we had a 2.5-hour session about only section 2.3.4.1. I doubt you&#x27;d be able to get this much content from a sub-sub-sub-section of CLRS.
