本文主要是介绍【路径规划】基于遗传算法求解多旅行商问题matlab代码，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1 简介

旅行商问题是一个经典的NP完全问题,多人旅行商问题的求解则更具挑战性.以往对求解多人旅行商问题的研究局限于以所有成员路径总和最小为优化标准,而对以所有成员路径最大值最小为优化标准的另一类多人旅行商问题却未加注意.文章给出了这两类多人旅行商问题的形式化描述,探讨了利用遗传算法求解这两类多人旅行商问题的基本思想和具体方案,进行了仿真实验验证.仿真实验数据表明,这是一种高效而且适应性强的多入旅行商问题求解方法.

2 部分代码

function varargout = guimtsp(varargin)
% GUIMTSP MATLAB code for guimtsp.fig
%     GUIMTSP, by itself, creates a new GUIMTSP or raises the existing
%     singleton*.
%
%     H = GUIMTSP returns the handle to a new GUIMTSP or the handle to
%     the existing singleton*.
%
%     GUIMTSP('CALLBACK',hObject,eventData,handles,...) calls the local
%     function named CALLBACK in GUIMTSP.M with the given input arguments.
%
%     GUIMTSP('Property','Value',...) creates a new GUIMTSP or raises the
%     existing singleton*. Starting from the left, property value pairs are
%     applied to the GUI before guimtsp_OpeningFcn gets called. An
%     unrecognized property name or invalid value makes property application
%     stop. All inputs are passed to guimtsp_OpeningFcn via varargin.
%
%     *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
%     instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
