createTrekSeparationIdentifier: Create an trek separation identification function

Description

A helper function for trekSeparationIdentifyStep, creates an identifier function based on its given parameters. This created identifier function will identify the directed edge from 'parent' to 'node.'

Usage

createTrekSeparationIdentifier(
  idFunc,
  sources,
  targets,
  node,
  parent,
  solvedParents
)

Value

an identification function

Arguments

idFunc

identification of edge coefficients often requires that other edge coefficients already be identified. This argument should be a function that produces all such identifications. The newly created identifier function will return these identifications along with its own.

sources

the sources of the half-trek system.

targets

the targets of the half-trek system (these should be the parents of node).

node

the node for which all incoming edges are to be identified (the tails of which are targets).

parent

the parent of node for which the edge node -> parent should be generically identified.

solvedParents

the parents of node that have been solved
