python - Solving tic-tac-toe through brute force -

-

i have been struggling problem while. need solve tic tac toe through brute force - is, having computer "learn" playing few million times.

right now, "setup" works - i'll briefly describe it. computer plays generating random moves, until 1 side or other has won. stores list represents game, , associates list 1, 0, or -1 win, draw, or loss.

the algorithm i'm using simple one; find move on board associated wins , least losses, out of games can result current board, , move there.

this works ever case; except important ones: forks.

in situation this:

o - -       o - x     o - x  - x -   >   - x -  >  - x -  - - o       - - o     o - o

where computer has next move, computer invariably goes in corner, , later gets forked.

is there way solve tic tac toe through "brute force" (without using min/max, heuristics, hard coding forks, etc.)?

a few million times may excessive. think there 362,880 possible "games" (statistics: first player has 9 options, next player has 8 remaining, 7, etc.. 9! = 362,880).

i recommend weighing move selection based not on eventual win/loss, on number of moves required win. fewer moves = better decision.

also, once build "complete" map, can map moves in situations "death" moves, leading inevitably loss. designed weighing metric see there no route win, , never select move (which include forks).

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
