This program is an example of a backward-chaining decision tree in Flex.

The example uses two frames:

  • one to facilitate the expert system's questions and answers
  • the other to show the current status of the execution

This second frame is automatically updated whenever a new answer is given.

The Flex code has been written in a generic way, and can be easily adapted to other areas.
