Randomized Hopcroft-Karp

Install

npm install randomized-hopcroft-karp

Usage

function findMatching(
  m: number,
  n: number,
  edges: [number, number][],
  groups?: number[]
): [number, number][];

• m: Number of nodes U.
• n: Number of nodes V.
• edges: Edges between U and V.
• groups: Groups which nodes U belong to. The algorithm tries to maximize cardinality of chosen groups.
• Returns an array of edges representing the matching.

Example

import findMatching from "randomized-hopcroft-karp";

const matching = findMatching(3, 4, [
  [0, 0],
  [0, 1],
  [1, 1],
  [1, 2],
  [2, 1],
  [2, 3],
]);
