Code and research for yourself. Sigh. The AI can help make a moron sound 
half way smart?

gcc-14 and clang-20 are certainly available on many (most ?) Linux
distributions. May be, getting them on some distros is less easy than
it is on Windows/msys2, but it is not a rocket science.

Availability of the GNU CC on Linux was not the problem with BM's code.
See Paul's reply for details.

It was, actually. Not on any Linux, but on your specific Linux
instalation.
Bonita said that her code compiles with gcc-14. I see no reason
to not believe her.

BTW, it was not Paul's reply, but reply of co-pilot. Which I don't
trust.

What she originally said was: "I show mine in C++23".

And I did:  g++ -std=c++23 -o ttt_bm ttt_bm.cc
and got errors.

> BTW, it was not Paul's reply, but reply of co-pilot. [...]

The point is that BM's code didn't compile with -std=c++23
and Paul's code - that fixes the issue - compiled well.

All that wouldn't have been necessary in the first place if
Bonita would have just shown her results - as she requested
also from the audience! - but no, not even after I asked for
that, twice.

Paul's response (with or without AI) was helpful - in *both*
respects, code and result! - Bonita's (and yours) were not.

(You can continue squirming around these obvious facts, but
don't expect that I'll respond to more useless rubbish like
that.)

Janis

BTW, providing some code is hardly evidence for the original
question. A formal mathematical deduction would be in order
to get any results to be verified. - Otherwise you can only
compare all programs' results and make guesses (or ask an AI -
which might be okay given that this is such a trivial "quest"
that had certainly be "solved" many times in every language,
so easily to be identified by the AIs - I've just tested that
and got code, code that compiles correctly and that produces
the equivalent results, modulo the symmetries, of course).

Since the code is in C++, please restrict followups to the appropriate
newsgroup.  Thanks.

Possibly a very famous assignment for students
doing computer science. But I have never ever
written a game.

It's not about writing a game but calculating the likhehood
of different outcomes.

But do you have to use beautiful maths to
solve maths problems? Could we just use
fingers and counting, like programming? :)

There is a game called "lights out."  I forgot the exact rules, but
it has lights on a grid, and toggling one toggles four others in a
cross pattern[1].  Some squares -- it depends on the size -- you can
solve exactly, and some have no solutions.  The "trick" here is to
create a program that does boolean matrix algebra, and then it can
tell you if the current board/position has a solution, or has no
solution.

The object of the game is to start with all lights on, and then turn
them all off.

Do you like to create programs that solve such games?

Your apparent obsession with me is annoying.  I intend this to be
my last communication with you.  Please consider not mentioning
me ever again.  (If you could refrain from making off-topic posts
to these newsgroups, that would be great, but I don't expect that
kind of self-control.)

You broke your own rule, and replied to me.  Do you have amnesia?

A player who doesn’t make mistakes is going to choose a losing move,
where there is a non-losing alternative available, with a likelihood
of zero.

That's not what I asked for.

That’s how tic-tac-toe is played, in case you didn’t know.

Prove your claim by stupid programming!!! :)

You sure how to play Tic-Tac-Toe?

Spoiler alert .....





















Okay, first one needs to define victory and draw.
Then, you can just iterate all possible endgames.
No actual calculations needed?

I recommend the exercise.  It's quite different from the "normal" type
of programming we do in every day programming.  At least, those of us
who don't work at gaming companies.

In comp.lang.c, I recommend starting with /SDL Game Development/ by
Shaun Mitchell.  I prefer that book over the lazy fu tutorial, or what-
ever it's called.

It should be trivial to port the code to SDL3.

That said, my professional game development "career" if we can use that
term, was limited to C# in then-Unity.  Since then, Unity has changed
license terms, so I can't recommend it anymore.

Maybe I'll make a commercial game in SDL one of these years.


There's no C# group that I know of, so I'll add comp.theroy instead.
