Prize policy
(We acknowledge that the original idea is essentially due to Donald Knuth)

  We are going to pay $8 to whoever solves any of our problems after October 1, 2002. If the same person solves another problem, he/she will get $16, then $32, etc., until we are broke. (It is hard to tell how much it will take to make us broke, but right now it looks like $512 would do it.) For OUTSTANDING PROBLEMS, there is a flat rate of $200 per problem.

Note:   parts (a), (b), etc. of a problem are considered different problems. In case of joint authors, the prize money will be split between the authors.
Example:   Suppose joint authors A and B solve Problem 1. Then both get $4. After that, joint authors B and C solve Problem 2. Then B gets $8, whereas C gets $4.

Important: For your solution to be qualified for a prize, either a relevant paper has to be accepted for publication in a refereed journal, or a preprint has to be posted online for at least one month, either on your homepage, or at some established e-archive (we recommend xxx.lanl.gov/archive/math). We do not run an e-preprint archive at this location.

We trust that if you (or someone else) eventually find a gap in your solution, you will return the money.
