CANDE Developers and Contributors

 

Dr. Michael Katona has been and remains the primary author and key architect of the CANDE program from its inception in 1972 to present.  Over the years, many engineers have made significant contributions in the theory and/or algorithms embodied in the program. Their contributions are acknowledged in chronological order in the table below.
