This article discusses the use of C++ hash containers to improve storage of subproblem results when using dynamic programming (DP.) Memoization is a key part of dynamic programming, which is conventionally done by storing subproblem results in simple tables or lists. Using hash tables instead of these simpler structures will allow you to use dynamic programming while retaining your algorithm’s natural recursive structure, simplifying design and making your code easier to follow. I’ll provide a fully-developed example of an algorithm, and show how it can be adapted to use hash table memoization.

Byte.comFebruary 9, 2004 Article on Byte.com I've been an ardent proponent of server-based digital media for a long time. Way back in 1999, technology finally reached the point where I could migrate my music collection from CDs to a server, with the result chronicled here.
