ArgMax

ArgMax[f,x] gives a position xmax at which f is maximized.

ArgMax[f,{x,y,…}] gives a position {xmax,ymax,…} at which f is maximized.

ArgMax[{f,cons},{x,y,…}] gives a position at which f is maximized subject to the constraints cons. 

ArgMax[…,x∈rdom] constrains x to be in the region or domain rdom.

ArgMax[…,…,dom] constrains variables to the domain dom, typically Reals or Integers.
