Tic Tac Toe Coding Challenge

I can't resist :

WRONG ! There is one situation where X lose at his third move...Therefore "all boards with up to four pieces are a draw" ;):D

Chilly, I guess I am missing your point.  It takes four marks in a row to "win" the game, so how can the game be over after the third move?

I won't change the template for the official competition.  Nothing says you have to use all the inputs provided, though.  They just need to be there so they fit into the tester template.

I do like the idea of having to start from random positions.  Even with the first one or two moves given as a random starting place, it would test the ability of the algorithms to recover from a stupid move.  I won't change the original method of play, but perhaps this could be incorporated as a tie breaker instead of fastest player.

CC & Altenbach have w-a-y too much (free) time on their hands....  😉

sigh 😐

Well, I should have said "X will lose (against a perfect player) whatever his further moves"...

You mean to tell me that there is a position containg two Xs and two Os that is a forced loss for X under the rules of the challenge?

Can you loose it against Deepest Toe (set to play to loose)?

If this is true, maybe my DT has some serious athletes foot (I did some cuts late in the development so it is possible that a bug snuck in). 😉

Sorry ! I mixed the relative moves. You are right, only the sixth move (for O) can lead to a loss ! That's the sort of mistakes you do while far from the board. Seems that I'm poor at mental TTT. I should stay with mental chess...

I apologize sincerely. How can I make up for this silly error ? I'm so disturbed now ! How terrible... That's all my fault !!!... Now were did I put that rope ?...

Would you like to borrow mine?*

Sorry could not resist.

Maybe one of the next challenges will be a LabVIEW based chess player, so this will come in handy. 😄

And I was pretty sure you were just trying to mess with my mind.. 😉

Instead of a rope, you could just use a wire, there should be a spool in the tools palette. (Unfortunaltely, it does not allow you to make any wire loops).

With a little imagination, Labview can do anything.

Many thanks to all of you for helping me to solve definitively my shame problem.

So here my method, using only standard LabVIEW objects :

- a tree

- a strong wire

- a loop.

You will notice that the stop button has been suppressed. Of course, when I press the run button, LabVIEW... hangs !

Errrkkk...
