以下是一个用C#实现TSP问题的基本程序:
```csharp
using System;
namespace TSP
{
class Program
{
static int[,] adjacencyMatrix; //邻接矩阵
static int[] visited; //标记是否被访问过
static int[] path; //记录路径
static int length; //记录路径长度
static int n; //节点数
static void Main(string[] args)
{
n = 4; //节点数
adjacencyMatrix = new int[n, n] { { 0, 10, 15, 20 }, { 10, 0, 35, 25 }, { 15, 35, 0, 30 }, { 20, 25, 30, 0 } }; //邻接矩阵
visited = new int[n];
path = new int[n];
length = int.MaxValue;
TSP(0, 1, 0);
Console.WriteLine("最短路径为:");
for (int i = 0; i < n; i++)
{
Console.Write(path[i] + " ");
}
Console.WriteLine();
Console.WriteLine("路径长度为:" + length);
}
static void TSP(int k, int count, int sum)
{
if (count == n)
{
if (sum + adjacencyMatrix[k, 0] < length)
{
length = sum + adjacencyMatrix[k, 0];
path[n - 1] = 0;
}
return;
}
for (int i = 1; i < n; i++)
{
if (visited[i] == 0)
{
visited[i] = 1;
path[count - 1] = i;
TSP(i, count + 1, sum + adjacencyMatrix[k, i]);
visited[i] = 0;
}
}
}
}
}
```
该程序实现了基本的TSP问题,其中邻接矩阵可以自行修改。运行后可以得到最短路径和路径长度。
