% Usage         : [Tmin, Tmax] = DeltaSolver(Diff, CR)
                     
% Description   : This function solves the delta_min and delta_max problem
 
% of the comparison procedure. There are two options for this [see
         
% OptionSet]: (a) use 'Approximate', which simply linearizes the objective
 
% function intelligently using a McCormick relaxation [for one of the terms
% to preserve convexity] or (b) use 'fmincon', which uses the MATLAB
       
% in-built function 'fmincon' to solve the problem. So far, 'fmincon' has
  
% proven to be quite robust for this [unlike the 'ExactSolution' function],
% however the computational effort is significantly higher!
