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 directly on the compressed representation, i.e. without decompression. Similar data structures include negation normal form (NNF), Zhegalkin polynomials, and propositio… WebEin binäres Entscheidungsdiagramm (BED; engl.binary decision diagram, BDD) ist eine Datenstruktur zur Repräsentation Boolescher Funktionen.Binäre Entscheidungsdiagramme werden vor allem im Bereich der Hardwaresynthese und -verifikation eingesetzt..

Please look at BooleanConvert with "BDT" (Boolean decision tree) and "IF" (If and constants) forms. – kirma.

BDD operations take time proportional to the size of the data structure, not the number of tuples in a relation, which leads to fast execution times. bddbddb is an effective tool for implementing a large class of program analyses. onpoint tax forms
