DOT - Design Optimization Tools

Unconstrained optimization and nonlinear programming

The DOT program uses the BFGS method for unconstrained optimization problems. For constrained problems, DOT implements a modified feasible directions algorithm (similar to a reduced gradient method), sequential linear programming, and sequential quadratic programming. Gradients can either be supplied by the user or obtained by finite differencing. A line search is performed along each search direction generated by one of the methods.

Software is written in ANSI Fortran and therefore is portable. DOT is the latest software written by the author of the CONMIN and ADS programs. DOT is fully supported and is used worldwide.
