function varargout = min(chr)
% MIN - Returns the value of the worst member in the population. Also returns
% the member and the index position in the vector if desired.
%   [val,mem,ind]=min(chr) The argument to the function is a vector
%   of type chrom, one generation.  The output is
%     mem - worst member.
%     val - fitness of worst member
%     ind - the index in the vector
%   
%   See also MAX,MEAN,MEDIAN,STD
[m n]=size(chr);
for k=1:m
  for l=1:n
    fit(l)=get(chr(k,l),'fitness');
  end
  [q f_ind]=min(fit);
  varargout{1}(k,1)=fit(f_ind);
  varargout{2}(k,1)=chr(k,f_ind);
  varargout{3}(k,1)=f_ind;
