Binary decision diagram algorithm
In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, BDDs can be considered as a compressed representation of sets or relations. Unlike other compressed representations, operations are performed … See more A Boolean function can be represented as a rooted, directed, acyclic graph, which consists of several (decision) nodes and two terminal nodes. The two terminal nodes are labeled 0 (FALSE) and 1 (TRUE). Each … See more BDDs are extensively used in CAD software to synthesize circuits (logic synthesis) and in formal verification. There are several lesser known applications of BDD, including See more Many logical operations on BDDs can be implemented by polynomial-time graph manipulation algorithms: • conjunction • disjunction • negation However, repeating … See more • Ubar, R. (1976). "Test Generation for Digital Circuits Using Alternative Graphs". Proc. Tallinn Technical University (in Russian). Tallinn, … See more The basic idea from which the data structure was created is the Shannon expansion. A switching function is split into two sub-functions (cofactors) by assigning one variable (cf. if-then-else normal form). If such a sub-function is considered as a sub-tree, it can be … See more The size of the BDD is determined both by the function being represented and by the chosen ordering of the variables. There exist Boolean functions It is of crucial … See more • Boolean satisfiability problem, the canonical NP-complete computational problem • L/poly, a complexity class that strictly contains the set of problems with polynomially sized BDDs • Model checking See more WebJan 1, 2024 · Decision diagrams (DD) are a widely used data structure for discrete functions representation. The major problem in DD-based applications is the DD size minimization (reduction of the number of ...
