>Please Programming it in C.
I don't think so:
It is against EE Policy to do homework!!!

 

by: tomyzhenPosted on 2003-01-21 at 05:13:55ID: 7769717

But,It's not homework,it's just a problem that I found in a C studing book,and it doesn't provide the key.That's why I come to ask...hopes you can help me,if you know the answer.

start at a given node. always choose the cheapest place you have not yet been to. If you get stuck, quit. Do this by starting at each node. The smallest / cheapest whatever path you find that completes is a solution. It is a good solution but not always the optimal one.  Also you may never get a solution for some graphs. But its a start. Or do the brute force thing if you want the true solution, but its very slow! there are a lot of sites on this one, its a classic problem.

But what's going on if I am only to start @ a certain  Point A? Can u provide the source code? Thx.

Look, tomyzhen.

Either you do know a bit of C, and then try to put your ideas (or someone else's) together and write a code, and after that, ask for help.

Or you have no clue in C programming, and in that case, a C "travelling salesman" source won't help. You need simpler examples.
