Day 8: CM, Page viii

Research Problems may or may not be humanly solvable, but the ones presented here seem to be worth a try (without time pressure).
- Concrete Mathematics, p.viii

Day 8: Another easy preface page. On this page, the authors describe the different types of problems. The problems range in difficulty from Warmup, to Basic, to Homework, to Exam, to Bonus, to Research. It sounds like the first four categories are solvable and the last two are less solvable, with the research problems possibly not "humanly solvable". My goal is to do the Warmup, Basic, Homework, and Exam problems. I'll probably need to spend more than a day on each of those pages.
