RAPTOR, the Rapid Algorithmic Prototyping Tool for OrderedReasoning, is a graphical authoring tool created by Martin C. Carlisle, Terry Wilson, Jeff Humphries and Jason Moore. The software is hosted and maintained by former US Air Force Academy and current Carnegie Mellon University professor Martin Carlisle. RAPTOR allows users to write and execute programs using flowcharts. The simple language and graphical components of RAPTOR are designed to teach the major ideas of computer programming to students. It is typically used in academics to teach introductory programming concepts as well.
