Abstract

We investigate graph-driven free parity BDDs, which strictly generalize the two well-known models parity OBDDs and graph-driven free BDDs.
The first main result of this paper is a polynomial time algorithm that minimizes the number of nodes in a graph-driven free parity BDD. The second main result is an exponential lower bound on the size of graph-driven free parity BDD for linear code functions.
