Exact frustration index of a signed network
Description
Computes the exact frustration index of a signed network using linear programming
Usage
frustration_exact(g, ...)
Arguments
g |
signed network |
... |
additional parameters for the ompr solver |
Details
The frustration index indicates the minimum number of edges whose removal results in a balance
network. The function needs the following packages to be installed: ompr, ompr.roi,ROI, and ROI.plugin.glpk.
The function Implements the AND model in Aref et al., 2020
Value
list containing the frustration index and the bipartition of nodes
