IcmChopNegotiationAnalysisResult

Returned by icmChopNegotiationAnalysis.

Field	Type	Meaning
chipChop	number[]	Chip-proportional split of total prize pool
icm	number[]	Harville ICM expected payouts
surplus	number[]	chipChop[i] - icm[i] per seat
totalPrizePool	number	Sum of payout ladder
paretoPairs	IcmChopParetoPair[]	Directed surplus-transfer edges

Semantics

chipChop[i] = (stacks[i] / Σ stacks) × totalPrizePool. icm is the standard Harville vector from the same stacks and payouts. Positive surplus[i] means a chip chop would overpay seat i relative to ICM; negative surplus means underpay. paretoPairs lists feasible transfers from surplus seats to deficit seats.

Example

const poker = require('poker-calculations');

const { chipChop, icm, surplus, paretoPairs } = poker.icmChopNegotiationAnalysis(
  [12000, 8000, 5000, 2000],
  [10000, 6000, 3000, 1000],
);

surplus.forEach((s, i) => {
  console.log(i, s > 0 ? 'surplus' : s < 0 ? 'deficit' : 'flat', s);
});
console.log(paretoPairs);
