If anyone doesn't know about the Probe software site, they have a very decent Stratego robot to play against. It's not the best, but I think could be ranked in the 300's. Try it if you haven't.

I'll try it sometime! But I'll probably lose; I'm only around 275. Playing vs. 300s will be tough. But I'm sure it'll be very good practice! Thx for sharing, Gary.

Yes, let us know your opinion on its strength, Fairway. It does stupid things, so know that, just not nearly so much as the site's single player does.

Haha yeah. I've seen the site run its marshal, general, and both colonels into the SAME and PREVIOUSLY KNOWN bomb. Pathetic. :-)

How can we ever get VdB's bot to play against, Max? Is it actually out for the public anywhere?

I would be killed against a bot like that. What is it, probably at least 500 ELO, right?

Unlikely. It's difficult for a bot to play on a higehr level due to the fact this game is so much more complex than the basic tactics in games like chess. In stratego you make "plans" rather than look at individual moves and tactics, which is harder for the computer to understand and calculate

 

Probe plays at around 250-300 ELO in my opinion.

Yes i think i said on another thread it is about ELO 280 perhaps.

 

The ELO of the computer here is about 20 as i'd expect even people who have never played and just spent 2 minutes reading the rules to beat it 4/5.

 

The failings of Probe are predictable movements . An important piece is always backed up . If you reveal a Colonel on your front row and Probe puts on unknown piece next to it you know it will be the Marshal or General , never a bluff .If you threaten Probe's known General,Colonel or Major with an unknown piece it always backs off .

 

Also it is quite inept at defending an open flag, you can sometimes just march a Sergeant straight to it in the middle of the game.

 

It doesn't give up important pieces (other than sometimes the flag  :rolleyes: ) for nothing though and if you reveal your Marsh and Gen too cheaply it will attack your other pieces quite efficiently  .

I'll try to find the place I saw it, but somewhere VdB's bot was rated 550. I don't know much about programming but this VdB fellow is a veritable genius. I'm not surprised if he could get it that high.

Vincent de Boer won the world stratego championship and then wrote the programming for his bot. See the following link: https://www.google.c...yGvMUExqBt1Vn7A

Max, I repeat my question about Vincent de Boer's bot. Is it available anywhere for the public, do you know? Can you verify what kind of ELO it was supposed to have?

Thanks,

Gary

I tried to find an answer to your question, Gary, and I was brought to a page with what appeared to be an app called: Legion Stratego Game. It says in the text that it's Engine was written by VDB.

There was also a link to a site for the app: Legion-The strategy of war . They claim to use vdb's program too.
Neither app came up in the iOS App Store.
Furthermore, a site called Master of the Flag claims to have had the best ai from 2007-2010

Yeah, texaspete09, I couldn't get any of those to come up in Android's Google Play either. But I did find two references in the web to Master of the Flag. The first one is a link directly to it. The second one below is from our very own site. (Note the designer of Master of the Flag responds at the end of the second link below.)

Hey, texaspete09, thanks for telling me about Master of the Flag.

I just played my first game of it. I must say, I thought it was pretty tough. I'd put this higher than Probe for difficulty but not nearly so friendly to play. MF does not allow you to save setups whereas Probe does. And the game aids are either on or off with MF. When on you see the pieces marked with a dot that have moved and actually numbered if you have struck them before. In other words they are always revealed once discovered. But if you turn off the aids in MF you'll never be told what the rank of the opponent's piece is that beats you. And that's a problem with MF.

Still, I found the play to be credible. I won but played a decent game and didn't make mistakes. I felt MF didn't make mistakes either. At least in this first go around. If everyone thinks Probe is around. 280 ELO, then I put MF at 380-420.

I think I posted about this in another thread. Master of the Flag is probably only about 300-325 ELO or so. If I REALLY want to beat it, I can do probably so 4/5 times but it's a good practice for bronze players.

Really? I'd say it's about 325 or so. I can beat it 4/5 times if I really want to. Then again, I can beat mid silver players if I REALLY want to and try my hardest.

Yeah, well Fairway, you may be right. I found it difficult but it was new and that's always a bit disconcerting. If you ever try playing at Gravon or Metaforge, it is very odd at first.

It will be interesting to see how others view this. It's a bit apples to oranges with the reveal of the pieces it gives you at MF, but I think it's a bit better than Probe. You think a bit less. It's just too bad MF doesn't tell you your opponent's rank after a battle. That's what is very unusual.
