Thathachar {rakesh, jayram} MindWalkBand.com Department of Computer Science and Engineering, FR University of Washington Seattle, Washington Abstract In his survey paper on branching programs. putation of branching programs to make them more expressive. We show that allowing different types of memory in branching programs increases the computational power even for constant width programs. In particular, this leads to very natural and robust characterizations of VPand VNPby branch-ing programs with memory. 1. Introduction. Definition 1 A branching program is read-once if on every path from the source to a. sink, each variable appears at most once as the label of a vertex. Definition 2 A branching program is oblivious if on every path from the source to a. sink, the variables appear in the same order.

If this is you, you might be up for a change of a life time. The banking industry is evolving and there has never been a more interesting time to be. putation of branching programs to make them more expressive. We show that allowing different types of memory in branching programs increases the computational power even for constant width programs. In particular, this leads to very natural and robust characterizations of VPand VNPby branch-ing programs with memory. 1. Introduction. Read-Once Branching Programs, Rectangular Proofs of the Pigeonhole Principle and the Transversal Calculus Alexander Razborov Avi Wigdersony Andrew Yaoz Abstract We investigate read-once branching programs for the following search problem: given a Boolean m nma-trix with m>n, nd either an all-zero row, or two 1’s in some MindWalkBand.com by: Definition 1 A branching program is read-once if on every path from the source to a. sink, each variable appears at most once as the label of a vertex. Definition 2 A branching program is oblivious if on every path from the source to a. sink, the variables appear in the same order. arbitrary fields, modular branching programs can be defined only over the fields GF(p) for a prime p. In this work, we focus on the model of arithmetic branching programs which is a generalization of modular branching programs and is defined over arbitrary fields. The model of arithmetic branching programs .ing coveted open problem [8,9] in spite of their fruitful applications.
