Check whether the current player won the game or not. However, two matters much reduce these numbers: The complete analysis is further complicated by the definitions used when setting the conditions, like board symmetries. As that linked page makes clear at the bottom, symmetry allows a reduction by a factor of $8$ (i.e. Why is sending so few tanks to Ukraine considered significant? Background checks for UK/US government research jobs, and mental health difficulties. The winner for a given board cannot have less cells than the loser since that means the loser just moved, despite the fact the winner had already won on the last move. However, positional games also include other possibilities such as the maker-breaker games in which one player (the "maker") tries to form a winning configuration and the other (the "breaker") tries to put off that outcome indefinitely or until the end of the game. Anyways, here is my solution in Swift 4, there are 8 lines of code for the combinations function and 17 lines of code to check a valid board. How does the case $n=7$ reduce to ordinary tic-tac-toe? Then if that square weren't filled, you would be moving to fill it, meaning that you're moving to some position $P_0$ where (by the assumptions) you're guaranteed to have a winning position. Has natural gas "reduced carbon emissions from power generation by 38%" in Ohio? I couldn't think well at that moment. You could apply this logic to determine if a board is valid or not: If there are multiple three-in-a-rows for a certain symbol, make sure they all overlap at the same cell.

There's actually another limitation in that it's impossible for one letter X or O to have won in two different ways without a common cell (again, they would have won in a previous move), meaning that: so I thought the invalid states are the states where we have two winning lines in the same direction(vertically or horizontally), this is wrong solution, there are states where there are two winning lines not in the same direction How to make chocolate safe for Keidran? So I would simply use brute force and, for each position where the difference is zero or one between the counts, check the eight winning possibilities for both sides. So, to get to the finish line as quickly as possible, attempt to catch the appropriate direction. Making statements based on opinion; back them up with references or personal experience.

The easy answer might be that the board is a $3\times 3$ square and so you are looking at the symmetry group of a square. Not the answer you're looking for? Is there a standard algorithm or common that should be applied to similar questions like this that I'm not aware of? The winner for a given board cannot have less cells than the loser since that means the loser just moved, despite the fact the winner had already won on the last move.

I'm unfamiliar with this generalization! Do peer-reviewers ignore details in complicated mathematical computations and theorems? How many winning configurations can you have in a nxn Tic-Tac-Toe game where players win if a they get n/2 in either a row or column, consecutively. They need to choose $-n$, which does not create any winning move for them, so we can choose $2$, creating two winning options ($-2$ and $-3$) [note due to $n \ge 5$ there is no interference with the earlier moves], and thus win. The game ends when three-in-a-row is obtained. This will naturally create a list (well, two lists) of no more than $304$ elements, because we only allocate memory to positions we actually encounter - but we never have to explicitly figure out which positions those are. Theoretical Computer Science Stack Exchange is a question and answer site for theoretical computer scientists and researchers in related fields. [2], This is a monograph, aimed at researchers in this area rather than at a popular audience. Alternatively, instead of finding the exact number of boards, you could just find some suitable upper bound and allocate that amount of memory.

How would I go about explaining the science of a world where everything is made of fabrics and craft supplies? However, in this game players can choose to place either X or O on each move One of the main results of the book is that somewhat larger grids lead to a "weak win", a game in which one player can always force the formation of a line (not necessarily before the other player does), but that grid sizes beyond a certain threshold lead to a "strong draw", a game in which both players can prevent the other from forming a line.
