Lee Jones has questions on ICM

From This Thread in MTT (http://forumserver.twoplustwo.com/showflat.php?Cat=0&Number=3876982&page=0&fpart=1&v c=1), dealing with using ICM to chop at a final table.

So, being ICM-clueless myself, I went to that page and read about it. Then I downloaded the C source, compiled it (Cygwin) without difficulty and ran it. It looked to my cursory glance like it was s'posed to determine the EV's for stacks of 18, 24, and 30 in a tournament down to three players with payoffs of .2, .3, and .5

So Q1: Are my assumptions correct?

When I ran it, it printed out:

72.000 0.25 0.3333 0.4166667

which seems to be:


total_chips %stack1 %stack2 %stack3

Then it went into a long waiting period and then spit out one row of numbers:

1816214400 0.250000 0.303571 0.446429 0.000000 0.000000 0.000000 0.305357

and a table. The table appears to be probabilities of people finishing in certain positions. But there's no guidance on how to interpret that.

In short, this program (presumably) does the heavy lifting nicely, but doesn't cross the t's and dot the i's, enabling a lay user to make much use of it.

(Even a comment or two tossed into the source would have gone a long way)

I may go have a look at the C++ source now and see if it's more useful. Does anybody wanna sell me a vowel?

Regards, Lee

So I grabbed the C++ source and tried to compile it. I get a gazillion compilation errors - it looks like maybe I don't have some include files I need (#include "vector").

Help.

Thanks, Lee

I figured that STT has a whole lot more experience with ICM and would better be able to answer all these questions.

ICM has no relevence heads up, each chip has the same value regardless of who's hands it is in.

i think even Lee (jk, lee) knows how to calculate equity Hu, his question about ICM is much broader then the original example I think.

Hm, I have no idea what those numbers are, heh. When I first saw it, I figured it was the equity for each player, given their stack size, but when I run the same numbers through an ICM calculator, it gets very different results.

[Slim Pickens]

All that's news to me. I've written an ICM calculator in Matlab (which is written in C I think) that works and is easy to understand, if that's any help here.
