Surrogate Optimization

Surrogate optimization solver for expensive objective functions

Use surrogate optimization for expensive (time-consuming) objective functions. The solver accepts only bound constraints, and requires finite bounds on all variables. The solver can optionally save its state after each function evaluation, enabling recovery from premature stops.
