import.m

一些用matlab编写的经典遗传算法算例 挺有用的

function pop = import(chr,fname)
% IMPORT - imports the fitness from a file
%   read this
res=[];
fid=fopen(fname);
mem=str2num(fgetl(fid));
for k=1:mem
  ids{k}=fgetl(fid);
  ids{k}=deblank(ids{k});
  ids{k}=fliplr(ids{k});
  ids{k}=deblank(ids{k});
  ids{k}=fliplr(ids{k});
end



while 1
  tmp=fgetl(fid);
  if ~ischar(tmp)
    break
  else
   res=[res str2num(tmp)];
  end
end

for k=1:length(res)
  ind=find_id(chr,ids{k});
  pop(k)=set(chr(ind),'fitness',res(k));
end

function ind=find_id(chr,id)
ind=0;
for k=1:length(chr)
  if strcmp(chr(k).id,deblank(id));
    ind=k;
    break
  end
end
