The Algorithm Design Manual , created by author Steven S. Skiena, which supplies links to implementations of more than 70 combinatorial algorithms. The site offers two features - unique material designed to complement courses offered at Langara and supplemented by the Raw List of useful links. The links are directed toward lower division college students and covers pre-calulus, calculus, and some differential equations.
All topics are cross linked for further investigation.
Most impressive feature is a regularly updated list of more than 1,000 links to math related pages on the Web, which is organized by broad subjects. The site offers impressive information, but the subject heading list is in no specific order making navigation troublesome.
