1. A non-transitory computer readable medium storing instructions that optimize a structure of a putter head for ball speed robustness, when executed by a processor, cause the processor to:
generate a plurality of face thickness points and a plurality of body thickness points using a sampling technique to fill a design space using a finite element analysis (“FEA”) program to generate a plurality of responses comprising a plurality of performance characteristics for the putter head;
generate a surrogate model from the plurality of responses comprising
generating a function for durability of the putter head from a finite element analysis (“FEA”) program of the putter head using the plurality of face thickness points for the golf club head and the plurality of body thickness points for the putter head,
generating a function for ball speed robustness of the putter head from the FEA program using the plurality of face thickness points for the putter head and the plurality of body thickness points for the putter head;
use the surrogate model in an optimization algorithm to provide an approximation of a lower sample space; and
repeat the above-mentioned steps until the surrogate model converges with the FEA for a predetermined objective to optimize the structure of the putter head for ball speed robustness.
