NArgMax
NArgMax[f,x] gives a position xmax at which f is numerically globally maximized.
NArgMax[f,{x,y,…}] gives a position {xmax,ymax,…} at which f is numerically globally maximized.
NArgMax[{f,cons},{x,y,…}] gives a position at which f is numerically globally maximized subject to the constraints cons.
NArgMax[…,x∈reg] constrains x to be in the region reg.
