function PI=GA_H248F(chro)
global MIN_offset MUL_factor 
% function PI=GA_H248F(chro)
% Fitness function evaluation 
% Fin max of a function of 2 varaibles
% Maximize f(x)=x1+x2 subject to
%    -2x1+x2<=3
%     x1+3x2<=16
%    4x1+x2<=20
%      x1, x2>=0
% chro is the input argument and is a vector of 2 elements
% MIN_offset, MUL_factor should be declared and values assigned
% before calling this function, such as
%   MIN_offset=0; MUL_factor=1;
% in the other program. However, if you want to use function
% alone,(both of the above varaibles are not declared
% before), this program will give you DEFAULT values as
%   MIN_offset=0; MUL_factor=1;   %<== DEFAULT
% CALLING example:
%   PI=GA_H248F([1.3 3.5])
