This volume gives a survey of the latest research in this field. It presents a branching program-based approach to complexity theory. Starting with a definition of branching programs and a review of the former research, nondeterministic branching programs are introduced and investigated, thus allowing the description of some fundamental complexity classes. The book then concentrates on the new concept of Omega-branching programs. Apart from the usual binary tests they contain features for evaluating certain elementary Boolean functions and are suited for characterizing space-bounded complexity classes. By means of these characterizations the author demonstrates the separation of some restricted complexity classes. In the appendix a number of extremely restricted graph-accessibility problems are given, which are, due to the branching program descriptions in chapters 1-3, p-projection complete in the classes under consideration. 410 0$aLecture Notes in Computer Science,$x0302-9743 ;$v370 606 $aProbabilities 606 $aComputers 606 $aAlgorithms 606 $aCombinatorics 606 $aProbability Theory and Stochastic Processes$3https://scigraph.springernature.com/ontologies/product-market-codes/M27004 606 $aComputation by Abstract Devices$3https://scigraph.springernature.com/ontologies/product-market-codes/I16013 606 $aAlgorithm Analysis and Problem Complexity$3https://scigraph.springernature.com/ontologies/product-market-codes/I16021 606 $aCombinatorics$3https://scigraph.springernature.com/ontologies/product-market-codes/M29010 615 0$aProbabilities. 615 0$aComputers. 615 0$aAlgorithms. 615 0$aCombinatorics. 615 14$aProbability Theory and Stochastic Processes. 615 24$aComputation by Abstract Devices. 615 24$aAlgorithm Analysis and Problem Complexity. 615 24$aCombinatorics. 676 $a519.2 700 $aMeinel$b Christoph$4aut$4http://id.loc.gov/vocabulary/relators/aut$0537947 906 $aBOOK 912 $a996465722903316 996 $aModified Branching Programs and Their Computational Power$92831459 997 $aUNISA
