Constructs a pseudo-conference matrix of order n using a determinant-based search procedure.

Description

Constructs a pseudo-conference matrix of order n using a determinant-based search procedure.

Usage

pseudoConference(n, starts = 1000, max.iter = 100)

Arguments

n	A positive integer specifying the order of the matrix.
starts	Number of random starting matrices used in the search. Default is 1000.
max.iter	Maximum number of iterations for each starting matrix. Default is 100.

Details

The matrix has zero diagonal elements and off-diagonal elements equal to -1 or +1. The search selects a matrix by maximizing the determinant criterion.

Value

A list containing the pseudo-conference matrix and the corresponding log-determinant value.

Examples

result <- pseudoConference(6, starts = 10, max.iter = 10)
result$Matrix
result$LogDet
