I would like to distribute a code for open-loop optimal control of time-dependent reaction-diffusion systems. The code is designed to solve for tracking and terminal observation problems also in combination with receding horizon techniques. The code is written in FORTRAN (santafe.for; santafe.dat is the input file), is public domain (therefore no guarantee) and a detailed description will appear in the proceedings of the Second Sandia Workshop on PDE-Constrained Optimization: Toward Real-time and Online PDE-constrained Optimization May 19-21, 2004 Bishop's Lodge, Santa Fe, New Mexico Workshop organizing committee: Larry Biegler, Omar Ghattas, Matthias Heinkenschloss, David Keyes, Bart van Bloemen Waanders.
