WebBinary Decision Diagrams More precisely, a binary decision diagram is a rooted, directed acyclic graph with two types of vertices, terminal vertices and nonterminal vertices. Each nonterminal vertex v is labeled by a variable var(v) and has two successors, low(v) and high(v). Each terminal vertex is labeled by either 0 or 1. 7/42 WebIs l Dillig, CS389L: Automated Logical Reasoning Lecture 5: Binary Decision Diagrams 31/37 Example 2 I Give the BDD representing the negation of the following BDD: Is l Dillig, CS389L: Automated Logical Reasoning Lecture 5: Binary Decision Diagrams 32/37 Nice BDD Properties: Canonicity I BDDs are acanonicalrepresentation of boolean formulas.
