Surrogate Optimization

Surrogate optimization solver for expensive objective functions, with bounds and optional integer constraints

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