Subject: Re: Please help!! From: Erik Naggum <email@example.com> Date: 1999/02/07 Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * email@example.com (Rainer Joswig) | It is a recursive problem. * Erik Naggum <firstname.lastname@example.org> | that's kind of intriguing. what distinguishes a recursive _problem_? * email@example.com (Rainer Joswig) | In this case we have a data structure (a Lisp list) that is easily defined | recursive. Recursive algorithms are very natural solutions | for problems like traversal, creation, filtering, etc. pardon me for insisting, but definitions, algorithms, implementations, and _solutions_ are easily described as recursive. my question relates to calling things recursive _problems_. if it is "a problem for which a recursive solution is deemed most aesthetic", it is just meaningless, but if it actually means something specific, I'd like to know. I find the term puzzling, apart from the more or less meaningless interpretation that doesn't refer to the problem at all. #:Erik -- Y2K conversion simplified: Januark, Februark, March, April, Mak, June, Julk, August, September, October, November, December.
