This is the web page of terms with definitions organized by area. That is, whether the term deals with graphs, trees, sorting, etc. We also list all entries with links to implementations and entries by type, for instance, whether it is an algorithm, a definition, a problem, or a data structure.

We need people to contribute. If terms are missing or you can add or correct definitions, please contact me by email (paul.black@nist.gov) or by other means.
