Hello people.  Sorry I haven’t checked back here in so long.
What with school and other projects, I don’t really have time to maintain this anymore with rule changes and such.  I would be happy to give someone the code if they wanted to give it a shot.

I have to warn you though, this app is not at all an easy one to maintain, for a few reasons:
1. Much of it is written like crap. I started the original version of this when I was pretty new to programming in general
2. No real documentation or comments at all.  What can I say, I never expected anyone other than me to be looking at it
3. The calculation algorithm is REALLY complicated.  I mainly wanted to to this for the challenge of it, but Monte Carlo methods (i.e. repeated dice rolling) are much more practical for this problem.  There are tons of unforeseen complications once you actually get into it.

@gamerman01:

Rip, this a very nice tool.
However, I’ve noticed that it’s not computing heavy bombers using 2 dice per bomber.  If I put in one heavy bomber attacking 2 units, there is a zero percent chance of both units being hit.  Do you guys use the house rule that you take the best of the 2 dice?  The default OOB rule is each heavy can get two hits because they roll 2 dice, and that’s the way most people play.  Any chance the tool can be updated for that?
I know you haven’t posted anything here for 6 months, but thought if I posted on your thread you might see it.
Thanks

should be fixed now

That bug should be fixed now.  I also made it so you can now use any number of defending fighters in a naval battle, since as someone pointed out the calc could be used half way into a battle once the carriers are already sunk.

Uhh sorry I haven’t been back here in a while, I’ll look into that bug and try to fix whatever other bugs people have been mentioning and post an updated version whenever I get a chance.

@Cmdr:

We need to clean up the code a bit, I think there’s a memory leak in the program. (If you have it on for a while, your computer slows down.)  Also, sometimes it won’t let you load fighters for your combat simulation (resetting them to zero).

It doesn’t let the defense in a naval battle have more fighters than it would be possible to fit on its carriers, if that’s what you mean.  As far as the memory leak, could you be more specific as to what you do when it happens, and what the memory/cpu usage are?  I tried keeping it open for various battles, and it stayed around 30MB mem usage and 0% cpu when idle.

If you see any other problems or lacking capability to run battles a certain way, feel free to give more input. 

Thanks for all the positive input. 
I’ve since updated it to fix a couple minor bugs, e.g. now only as many ships will bombard as there are units amphibiously attacking.

I’ve never played the game, but something that tends to help with older games is running in a compatibility mode.

Just right click the .exe > properties > Compatibility tab > run in compatibility mode check box > Windows 98 > OK

@Adlertag:

only whimps use odds calculators 

real men gamble  8-)

We mainly just use it after the game is over, so the losers can enter battles that were already played and complain about how unlucky they got.  :roll:

Well the group I play with recently bought the anniversary edition, and since no one else seems to have made one so far, I updated my calculator for the new rules like different unit values, bombardment not insta-kill, planes not hitting subs without destroyers present, ect.

You can get all the possible results by pressing the details button.  Just hold the mouse over to see what units are left for each outcome.
You will need Java installed to run it.  It should work on any OS.

New version - fixed bug with heavy bombers.  Also it should run slightly faster now

Sorry for the slow response, obviously I haven’t been on here in a while.

mshih:  You idea looks like it would work very efficiently, except that the order of loss is not determined.  Things like AA guns, subs only hitting ships, and in AA50 planes not hitting subs unless destroyers are present would make this extremely complicated.  It might still be possible to make a more efficient algorithm using a very complicated implementation of this, but I’m not going to be the one to do it.
