Can you suggest a source (preferably online) on data structures?[using pseudocode or c++]
I want to spend some time working on AI,to add AI to checkers or chess.I know/guess its not an easy subject,but I need a starting point.
There are tons of sites and articles on data structures. They are not textbooks though. Some familiarity with algorithmic analysis is usually presumed for the more complex subjects. Wikipedia, no matter what one says of its content, is good central hub with references and descriptions for orientation. Some of the articles there are very accessible, some are very cryptic. If you have some particular problem with the sources you find, then I(we) could try to help you specifically with that.
