chrom.m

一些用matlab编写的经典遗传算法算例 挺有用的

function c = chrom(varargin)
% CHROM - Constructor for the chromosome class
% This is the corner stone data type that the genetic tools operate on.
% It has four fields that contains all necsessary data.  
%     ____________________
%    | --------  -------- |
%    || NAME   ||FITNESS ||

% A chromosome is created by calling the constructor.
% c=chrom('name',cdvs,ddvs) or c=chrom 
% In the first case a chromosome is created with the properties
% supplied in the function call.  cdvs and ddvs are the continuous-
% and discrete design variables repsectively.  The 'name' is a
% string that identifies a chromosome. This to allow multiple
% species in a population. Note that the FITNESS is never set. It
% is always initialized to an empty matrix.  Calling the
% constructor without any arguments creates an "empty" chromosome.
