Software Demonstrations

  1. Several interactive demonstrations of software are available on the World Wide Web at http://www.cs.utexas.edu/users/novak:
    1. Automatic Programming Server: This system can accept descriptions of the user's data, make views of user types as abstract data types, and generate versions of generic procedures that are specialized for the user's data. The specialized procedures can be delivered in Lisp, C, C++, Java, or Pascal.

    2. VIP: This system generates scientific programs from diagrams of physical and mathematical principles and connections between equal quantities.

    3. Unit Conversion Server: Any combination of physical units can be converted to any equivalent combination.

    4. ISAAC: This program solves physics problems stated in English.
  2. Videotape demonstration at 9th Knowledge-Based Software Engineering Conference (KBSE-94), Monterey, CA, Sept. 20--22, 1994.
