R Documentation

Computes a stable roommate matching

Description

This is the C++ wrapper for the stable roommate problem. Users should not call this function directly, but instead use roommate.

Usage

cpp_wrapper_irving(pref)

Arguments

pref

is a matrix with the preference order of each individual in the market. If there are n individuals, then this matrix will be of dimension n-1 by n. The i,jth element refers to j's ith most favorite partner. Preference orders must be specified using C++ indexing (starting at 0). The matrix pref must be of dimension n-1 by n.

Value

A vector of length n corresponding to the matchings that were formed (using C++ indexing). E.g. if the 4th element of this vector is 0 then individual 4 was matched with individual 1. If no stable matching exists, then this function returns a vector of zeros. @export
