Utility function for searching DAG

Source: R/08B_GA_utils.R
maxParents_penalty.Rd

Function to limit the number of parent nodes

Usage

maxParents_penalty(vec, testlength, maxParents)

Arguments

vec

gene Vector corresponding to the upper triangular of the adjacency matrix

testlength

test length. In this context it means a number of nodes.

maxParents

Upper limit of number of nodes.

Details

When generating an adjacency matrix using GA, the number of edges coming from a single node should be limited to 2 or 3. This is because if there are too many edges, it becomes difficult to interpret in practical applications. This function works to adjust the sampling of the randomly generated adjacency matrix so that the column sum of the upper triangular elements fits within the set limit.
