Post subject:  Looking for an android AI
I'd like to buy one of the go AIs for android (my DGS opponents don't answer quick enough :) ).

Ideal characteristics:
- Work both on a phone and a tablet. (deal breaker)
- Have the option to use the machine's processor but also to call a server for extra strength.
- Have the option to take as long as it wants to make a move if/when playing locally.

Does something like this exist?

[options:]
crazy stone: I think it has the "31mb install, no app2sd" problem that essentially means I'd have to empty half my phone to make space for it.

It's worse than that. You describe yourself as being 3k. Best use of computer programs as opponents is to have them set to be a couple stones stronger than you are in which case you won't be learning bad habits related to your own level.

But it is far from clear that an Android device will have enough crunch power for a MCTS based program to function properly. I don't think any of them when playing on a device like this are more than a couple kyu. The problem is "not linear". You need at least a certain amount of crunch power for the algorithm to work at all as they are based upon statistics and that's very non-linear with respect to sample size.

"Call a server" is an entirely different question. Then the go playing program is not running on your Android device at all. All your Android or phone is doing is acting as a communicator to a remote application running on the server. Plenty of power for that, but like I said, an unrelated situation however similar it might appear to you from a user standpoint.

Crazy Stone running on an iPad 3 hardware at the max setting (higher than the max setting available on my Android phone) can't beat an EGF 2k friend of mine in an even game. I'm not sure how good a game you'll get with a phone running Champion Go. There's no Server option in the Android phone app that I have either.

Ok. I'll have to play more simultaneous DGS games while I wait for a "call home" android AI.

Maybe I should try OGS and its conditional move trees feature.

Thanks for the info guys.

Might be worth it to look into some servers that have stonger bots and play them using the android client. Something like KGS. Though the bots are often in use. There may be other servers, like oro maybe that has an android client and additional bots. Pandanet has bots avalable all the time, but they are not very good.

That's a good idea, turn based bot games might be the solution I was looking for. I could even upload my own bot on a desktop machine somewhere.

Alguien, not sure if you know, but both DGS and OGS have apps for Android.

Yes. I'm constantly playing DGS on my phone and I'm thinking about playing on ogs too. But it's hard to find people who would consistently answers moves "fast" (5~10 minutes per move).
