Binary decision tree

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 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 Many logical operations on BDDs can be implemented by polynomial-time graph manipulation algorithms: • See more • Ubar, R. (1976). "Test Generation for Digital Circuits Using Alternative Graphs". Proc. Tallinn Technical University (in Russian). Tallinn, Estonia (409): 75–81. • Knuth, D.E.

A switching function is split into two sub-functions (cofactors) by assigning one variable (cf. if … 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 fault tree analysis, Bayesian reasoning, product configuration, and private information retrieval See more • Boolean satisfiability problem, the canonical NP-complete computational problem • L/poly, a complexity class that strictly contains the … See more WebApr 7, 2016 · Creating a binary decision tree is actually a process of dividing up the input space. A greedy approach is used to divide the space called recursive binary splitting. This is a numerical procedure where all the values are lined up and different split points are tried and tested using a cost function.
