Battle Calculator oddity

@lennardf glad i could help :)

@axis-dominion Yes, this should be filed to the project, indeed.

Edit: I just see, that simon33 has already done it.

@CaptainNapalm Thank you for the savegame.

Indeed, when I use your savegame the situation appears to be resolved incorrectly.

However I have recreated similar scenarios using the current TripleA pre-release (2.3.21385) on different maps (including BM3). All of those have been resolved correctly.

So there was

a question to attack or not a question to submerge or not correct surprise strike execution

That brings me to the following conclusion:

Either there has been an issue with the engine (what I doubt but cannot exclude for sure) but the issue has already been resolved with current versions or there is an issue with your game that contains some triggers that might have somehow messed up the correct resultion of the situation (what I cannot examine in depth, knowing too little about that specific game).

So I recommend to

install and run the latest TripleA-version and the latest map-version begin a new game and see if that issue occurs again

Maybe @regularkid wants to take a look into it, too.

@FMErwinRommel Good find! As in Global “UK Pacific units” simply do not exist.
By the rules “All combat moves, combat, and noncombat moves are made or conducted as any other power’s single, united force.”
So the TripleA battle calculator seems to somehow “sort” those units depending on whether they are on the European side of the map or on the Pacific side of the map.

Interestingly this does not occur with sea units. Those are correctly represented as being “British”, even on the Pacific side of the map.

@redrum :

In the attached savegame please use the BattleCalculator and look at SZ 37 and 39. The UK ships are correctly represented as “British”. The Infantry units in Malaya instead are incorrectly represented as “UK Pacific”, while they should be “British”, too. Switching to “British” sets everything to “Zero”. This is not exactly @FMErwinRommel 's scenario, but good enough to represent the issue.

@FMErwinRommel I have moved this topic to the TripleA category, as this is a TripleA feature and unrelated to the forum itself. :smiley:

Here is the related discussion on triplea-game.org

@ShadowHAwk:

This will actualy affect the outcome of your battles a lot and your calculation will be off.

2 inf + 1 bomber have the same attack value as 3 art. But if putted against 3 inf the 2 inf + bombers comby has a slightly higher chance to win.

Of course, because you’re losing 2 attack power with the first two casualties instead of only 1, and the 4 remains until last instead of a 2.

First of all, my approximations with carriers or tacs are done normally in much larger battles than 3 on 3 and the error is in fact negligible.  Again, the point is to get a probability distribution which Triple A doesn’t provide.  None of the good calculators I’ve found have been updated to accommodate G40.

My approximations using bombers in place of infantry/AAA is pretty accurate, because in almost all cases those units will be eliminated in the first round of the battle.

@Hepps01:

Remember the calculator is simply calculating the odds of victory or loss based on casualties from weakest to strongest in attack or defense value.  meaning it is removing the weakest units first followed by better ones later.

That’s about what I suspected, thanks!

I have seen other calcs out there but I like froodsters the best. On thing I learned in the Army was KISS (Keep It Simple Stupid) His calc sure does that.  :-)
