WebBinary Decision Diagrams (BDDs) [4] and their variations are a known representation of Boolean functions used in various practical applications, in particular, those related to computer-aided design (CAD). For example, in formal verification, the state space of a discrete system can be explored by representing and manipulating the transition WebIn this paper we consider the applicability of multi-rooted binary decision diagrams for the probabilistic model checking. The symbolic probabilistic model checking involves manipulation of functions and matrices with the values in [0,1], and multi-terminal binary decision diagrams, sparse matrices, and combinations thereof are used to represent … 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 green day paradise chords
