This article is from the Puzzles FAQ, by Chris Cole email@example.com and Matthew Daly firstname.lastname@example.org with numerous contributions by others.
Below is a list of puzzles, categorized by subject area. Each puzzle
includes a solution, compiled from various sources, which is supposed
to be definitive.

In keeping with the general net practice on FAQ's, I do not as a rule assign
credit for solutions. There are many reasons for this:
1. The archive is about the answers to the questions, not about assigning
2. Many people, in providing free answers to the net, do not have the time
to cite their sources.
3. I cut and paste freely from several people's solutions in most cases
to come up with as complete an answer as possible.
4. I use sources other than postings.
5. I am neither qualified nor motivated to assign credit.
However, I do whenever possible put bibliographies in archive entries, and
I see the inclusion of the net addresses of interested parties as a
logical extension of this practice. In particular, if you wrote a
program to solve a problem and posted the source code of the program,
you are presumed to be interested in corresponding with others about
the problem. So, please let me know the entries you would like to be
listed in and I will be happy to oblige.
