parallelHandSimulation

Same with worker threads and distinct seeds per chunk.

parallelHandSimulation(holeCards: CardInput, board: CardInput, numSimulations: number, baseSeed: number, villains: number, numThreads: number): number

CardInput is string[] or Uint8Array of deck ids 0..51. See Card notation.

Import

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

ESM (Node):

import { createRequire } from 'module';
const require = createRequire(import.meta.url);
const poker = require('poker-calculations');

When to use

Use on multi-core servers when simulateHandOutcome is CPU-bound and you want the same MC model with higher throughput. Each thread advances baseSeed so chunks stay independent.

How to use

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

const equity = poker.parallelHandSimulation(
  ['As', 'Ks'],
  [],
  200_000,
  9001,
  1,
  4,
);
console.log(equity.toFixed(4));

Board length may be 0–5; known cards must not overlap between hero and board.
