FindMinValue[f,x] gives the value at a local minimum of f.

FindMinValue[f,{x,x0}] gives the value at a local minimum of f, found by a search starting from the point x=x0. 

FindMinValue[f,{{x,x0},{y,y0},…}] gives the value at a local minimum of a function of several variables. 

FindMinValue[{f,cons},{{x,x0},{y,y0},…}] gives the value at a local minimum subject to the constraints cons.

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