Although some of these are quite difficult (involving, say, dynamic  
programming/optimization techniques), here is a huge inventory of  
problems associated with the Programming Challenges:

http://online-judge.uva.es/problemset/

scroll done to the catalogs. There are hundreds of problems. The  
downside is, of course, that there are no canoncial ruby solutions.

There is a book for them which you don't need but does demonstrate  
how some of the different kinds of problems might be solved: http:// 
www.programming-challenges.com/pg.php?page=index

It would be very interesting to see the solutions to these problems  
expressed in a rubyiomatic idiom. (I wonder if they could be  
convinced to add Ruby as one of the permissible languages? If not  
maybe the ruby community could implement their own?)

Cheers,
Steve
