When to use​

You need the full finish distribution per player (1st through nth) for custom payout structures or visualization. Row i is player i; column 0 is first place.

How to use​

const stacks = [5000, 5000, 2500];
const matrix = poker.icmHarvillePlacementProbabilities(stacks);

console.log('P(player 0 wins):', matrix[0][0]);
console.log('P(player 2 last):', matrix[2][2]);

console.log(poker.icmTopKFinishProbabilities(stacks, 2));
