challenge problem for the evening: generate palindromes!

alexr — Wed, 29 Feb 2012 05:01:08 +0000

What’s the longest palindrome you can produce entirely out of words in
/usr/share/dict/words ? (or some other finite word list?)

- Spaces don’t count; the string, minus spaces and punctuation, has to
be a palindrome.
- Don’t use the same word more than once.
- Bonus points for constructing something syntactically valid-ish, but
that seems hard.

Something of a classic; I guess I was thinking about Peter Norvig.
