This code allows the self-matched option
Gale_Shapley(U, V, return.data.frame = FALSE, cpp = TRUE, nmax = 10 * nrow(U))
The function return depends on the return.data.frame
value.
If TRUE, it returns
a two-column data.frame
with the first column a women's index and the second column the
men's index of their partner. It has as many rows as there are partnerships.
If FALSE, it returns the following matrix:
If cpp=TRUE
, a vector of length the number of women (nrow(U)
) with the
index of the matching man (i.e., the index is the row in V
of the man). If there is no
matching man, the index is 0. This can be used to reconstruct the matching matrix.
If cpp=FALSE
, the matching matrix, where 1 represents a pairing, 0 otherwise.
Each row is a woman, each column is a man. The order of the rows is the same as the
rows in U
. The order of the columns is the same as the columns in V
.
The utility matrix for the women's side. Each row is a woman, each column is a man.
The matrix entry (i,j) is the utility that woman i
gains from pairing with man j
.
In other words, the utility is computed from woman i
's perspective.
The utility matrix for the men's side. Each column is a man, each row is a woman.
The matrix entry (i,j) is the utility that man j
gains from pairing with woman i
.
In other words, the utility is computed from man j
's perspective.
logical Should a data.frame
of the matching be returned instead of the
paring matrix mu?
logical Should the Rcpp
version of the code be used. This is much faster and uses a lot less memory.
count The maximum number of iterations of the inner loop within the Gale-Shapley algorithm. This can be reduced to speed up the algorithm at the potential cost of many partnerships being non-equilibruim.
