Description
Implements the Field Code Forest (FCF) algorithm of Garfinkel et al (1986) to
derive all essentially new implicit edits from an editarray. The FCF is really
a single, highly unbalanced tree. This algorithm traverses the tree, pruning many
unnecessary branches, uses blocks to divide and conquer, and
optimizes traversing order. See Van der Loo (2012) for a description
of the algorithms.
Usage
1
Arguments
E
An editarray
Value
A 3-element named list, where element E is an editarray containing all
generated edits. nodes contains information on the number of nodes in the tree and vs the number of nodes
traversed and duration contains user, system and elapsed time inseconds.
The summary method for editarray prints this information.
