So, once again you assert that there is no way to optimize an unconstrained 
3-parameter problem with global minima.  Many minimization problems are not 
looking for a microscopic dirac in infinite 3D.  I suppose we could assume 
that's that kind of function the OP is presenting, or we could assume that 
his problem is not of that sort, and is much more mundane.  

The only way we'd know is to try, or to get more explanation from the OP.  
Perhaps he could provide a "realistic" range for A.  Even if A can be 2e6, 
its still a finite problem.
