FileName [mtr.h]
PackageName [mtr]
Synopsis [Multiway-branch tree manipulation]
Description [This package provides two layers of functions. Functions
of the lower level manipulate multiway-branch trees, implemented
according to the classical scheme whereby each node points to its
first child and its previous and next siblings. These functions are
collected in mtrBasic.c.<p>
Functions of the upper layer deal with group trees, that is the trees
used by group sifting to represent the grouping of variables. These
functions are collected in mtrGroup.c.]
SeeAlso [The CUDD package documentation; specifically on group
sifting.]
