WebFeb 14, 2024 · We employ the PMFG method [ 25] to construct networks based on cross-correlation matrices . The PMFG algorithm converts the dense correlation matrix into a sparse representation. The algorithm is implemented as follows: (i) Sort all of the in descending order to obtain an ordered list . (ii) WebThe PMFG algorithm [3] searches for the maximum weighted planar subgraph by adding edges one by one (see [5]). The resulting matrix is sparse, with 3(p 2) edges. The algorithm starts by sorting by weighting all the edges of a dense matrix of weights in non increasing order and tries to insert every edge in the PMFG in that order.
