Relocation Heuristic for Relaxed Structural Balance

Description

This function runs relocation heuristic for relaxed structural balance on an M x M asymmetric matrix. The main diagonal is ignored.

Usage

rhrsbt(A, C, TLIMIT)

Arguments

A

An N x N signed network matrix.

C

The number of clusters (1 < C < N, where N is the number of nodes).

TLIMIT

A desired time limit.

Value

The function returns the following:

• obj - the Doreian & Mrvar objective value;

• P - N-dimensional vector of cluser assignements; and

• restarts - the number of restarts within the time limit.
