Replace MFMC analytic allocation with a numerical solution
Alias: none
Argument(s): none
Unconditionally employ a numerical solve for allocation of samples per model instance within multifidelity Monte Carlo (MFMC). The analytic allocation is replaced with numerical solution using either sqp
or nip
solvers.
Usage Tips An unconditional override can be appropriate in the case where you select a pilot sample that may be larger than the anticipated optimal sample profile results (pilot over-estimation). In this context, the numerical optimization has greater freedom to work around the incurred pilot cost and find a solution that optimally incorporates the pilot.
