It’d be fun to train an AI using pro games. I wrote an AI once, but it was for Connect Four (a very simple game) and many years ago.

The 90 second delay for doing a second post on this forum is extremely annoying. Please remove it.

Also how can I get rid of it? I’m using my old forum account with 200+ posts from 2007 and for some reason I’m being treated as a potential spammer.

Here we might have another different view point. For me, if you have the choice between a battle with 51% win rate and positive TUV (even +1) vs doing nothing, so long as it doesn’t have a negative impact on your position - you take the battle.

You take all battles with positive expected outcome. And of course you’d favor the 52% win battle with 0.1 more TUV over the 51% one.

Unlike some/most gambling (I gamble on politics at PredictIt), there aren’t any “house” fees - so the tiniest imaginable edge is useful.

Unless you expect to beat your opponent by a large margin, in which case taking fights that are only slightly favorable to you might be detrimental.

The critical fact about attacking with 50/50 odds, is that with strategic withdrawal the battle simulators might be under-estimating your TUV gain (it’d be interesting if someone were to write a calculator that would handle that!). Admitedly this is a rare situation and you are much better off attacking at 95%+ win odds most of the time.

Uh oh. Different sounds bad

Has anyone made a dice simulator for G40?

This is my second ever Sea Lion attempt. First was in the Europe 1940. Hmm, might be easier for the US to take it back in Global. I feel sad for the transports!

I see the Triple A one. I like some of the functionality/stats of the older one more.

I saw that potential problem, but wanted to bail out the Italian fleet. Though perhaps the cost is too high? I’m thinking I’ve got a 5% chance of winning this game.

@Imperious-Leader The proposed model wouldn’t be that effective at handling stupid moves, and mistakes.

You could partially control for mistakes with a variable that is based on the player’s league ranking (if they are in the league).

As the lowest ranked Tier 1 (3.5 avg, but just won another game and am currently winning another and tied in a third that just started), I’m happy to see that I made it out of the lowest Tiers successfully. So my fears that the system would vastly under-exaggerate my true rank were overstated. I’d also like to thank the dice, Triple A, and my dual monitor setup.

@Imperious-Leader Statistical models predict things to be more likely than not. They can still be wrong. They aren’t perfect. If some idiot builds only naval units, or if someone decides to throw the game - it won’t work. (It also won’t work if the sample is too biased, or too small or half a dozen other reasons).

A classic example is that 538 model had Trump with a 20% of winning the US presidential election. Now I really don’t want to get into any political discussion, but it was completely possible that even though the 538 model favored Clinton, that Trump could still easily win. Any Axis and Allies player will be able to tell you how often unlikely events happen (so far my most unlikely dice roll was 1 in 100,000).

My background: I’ve always been fascinated by statistics. At age 5 I won a contest estimating the number of smarties (M&Ms but it was in the UK) in a jar. I was reading the World Almanac at age 11. I wanted to be an economist at age 12. I ended up with a MA in Sociology. I’m a part-time professional gambler since 2016 on PredictIt (and have consistently made money for the past 5 years). Though I’m only familiar with linear and logistic regression. There might be better techniques to use (and if so I’d be happy to hear about them).

My hypothesis is that among good players, positioning leads to IPC gains and can be modeled. I haven’t tested this hypothesis in Global 1940.

I used edit mode to add a German sub to SZ125. Then hit “Refresh Objectives” button on Triple A. And the objective switched to False.

This is generally a nice writeup!

For new players, I’d say the dice simulators are your friends and would totally disagree with this:
“SIDEBAR: Battle Dice are not your friend!”
It’s only as a more advanced player that you need to worry about this. Otherwise if you maximize your TUV everywhere, you ought to do well.

Under strafing, a similar move is to attack at 50/50 odds when you have a good place to retreat in the hope that the first round will go in your favor allowing you to press the advantage. Especially useful for battles with a small number of valuable naval units (assuming you can retreat to a safe spot). Though not a beginner move. So long as your one round strafe simulation looks ok, the attacker often has an advantage when attacking at 50/50. This is less true in land battles that are 50/50 where the attacker is typically losing more units on the first round that the defender is (infantry that attack at 1 and defend at 2).

Interesting estimations on unit value. We could put this to a test with logistic regression models

Oops SZ5, not SZ 125.

It has to be an enemy warship. So Japan has to be at war with Russia (which then triggers +2 for all three of their Land and Lease NOs).

Oops I’m skimming.

It’s interesting that the old transport (with defense of 1 and 1 usable HP) would be worth an additional $4.5 under these pricing scheme. I used to love mass transports in Revised.

I’m assuming that was a test post. If it’s your real saved game, let me know.

This is without the fighter.

Somebody could run statistics on the games for the past year or two. You’d need a decent sample size because the G1 turn and even J1 turn (if you do J1 attack) can swing it a good bit.

As a relatively newcomer, I’ve got little idea as to what a fair bid was. I heard 8 and went with that.

The bid might also depend on your level of play. It’s possible that one side requires more skill (though I’d have no idea who, other than the first G1 and J1 attack turns being a bit overwhelming if you are new).

A much simpler approach is to just look at the overall Axis and Allies win rate. Or see if the best players are playing the Axis more often.

I had some good rolls this round. No losses on my two SBRs, nothing lost to convoys, and killed two destroyers without losing any planes. No big battles, but a lot of helpful little ones. The ritualistic sacrifices to the Dice Gods are clearly paying off!
