File I/O from Squirrel

[wilco_moerman]

Hi, I am trying to create an AI for the TJIP contest, and I was wondering whether the NOAI framework allows writing to/reading from files? And if so, if someone could give me a short example?

It doesn't allow that. The only thing you can write text to is de console (and the ingame ai debug panel). You can do that by using AILog.Info/Warning/Error.

thanks for the reply. I guess I'll just have to use the script mechanism to output the console to a file, and copy-paste from there to my code.

In case you were wondering: I want to tune my AI by learning values for some of the decisions, and it would have been nice if I could just write them to some file and load them when needed.

OK, any idea when it will apear on http://nightly.openttd.org/noai/scoreboard.php? Because that is still r13442 instead of r13454

Nightlies run every night at 1800 CEST ... and the commits are made after that So check back in ... 10 minutes

Thanks for reporting and please keep posting any bugs here or on flyspray. If you want a fast reaction or follow latest development, irc is a good place (#openttd.noai @OFTC).

maybe I'll do that.

Avoid FlySpray, I don't read that I hope to have a subforum soon, then this will get a bit more organized

I wanted to start a server with restart_game_year = 2007 and starting in 1998 (for the TJIP challenge) and just let it run all night for testing. But if the game crashes after each "newgame" that won't work.

I am trying to implement an AI using a neural network, but networks need a lot of runs to train. That is why I need to start new games and save and load data. The network needs to be stored and loaded between each run. The saving works by using the console to output a script. I'll try to do the loading by modifying the .nut-files automatically using some Java-programming. I'll just get the parts I need from the console-output and substitute them into the .nut-file.

It might be ugly, but as far as I can see it's the only way to transfer information between successive AI's.

It most likely is Good luck with using a NN for this problem ... I wonder if it ever leads to anything Can't wait to see if it does

I'm counting the seconds

yeah I read the topic on that. Seems only logical.

It most likely is

at least as long as NOAI doesn't implement any file IO

I'll let you know. I have successfully used a NN together with reinforcement learning for my master's thesis, so I thought I would give it a try.
