FindArgMax

FindArgMax[f,x] gives the position xmax of a local maximum of f.

FindArgMax[f,{x,x0}] gives the position xmax of a local maximum of f, found by a search starting from the point x=x0. 

FindArgMax[f,{{x,x0},{y,y0},…}] gives the position {xmax,ymax,…} of a local maximum of a function of several variables. 

FindArgMax[{f,cons},{{x,x0},{y,y0},…}] gives the position of a local maximum subject to the constraints cons.

FindArgMax[{f,cons},{x,y,…}] starts from a point within the region defined by the constraints.
