WebThe polynomial identity testing problem (PIT) is a fundamental problem in Complexity Theory, as it is one of the few problems for which there exists a polynomial time randomized algorithm, but no deterministic sub-exponential time algorithm has been discovered. More- over, many fundamental algorithmic problems can be reduced to …

WebLECTURE 8. BEYOND THIS COURSE 44 perhaps the most fundamental language known to be in BPP but not known to be in P is polynomial identity testing, PIT = {h p, q i: p, q are identical multivariate polynomials}. • Interactive proofs As we saw in our study of polynomial-time veri-fiers, the study of NP can be viewed as a form of proof complexity: … Webfor which there is no known polynomial time deterministic algorithm is that of testing polynomial identities. The problem takes as input two polynomials Q and R over n …
WebIn particular, when the circuit is of polynomial (or quasi-polynomial) size, our algorithm runs in quasi-polynomial time. Prior to this work, sub-exponential time deterministic … Webis a deterministic polynomial identity test for multilinear read-k formulae of size sthat runs in time poly(s). In addition, there is a deterministic blackbox test that runs in time sO(logs). Note that Theorem 1.1 extends the class of formulae that Shpilka and Volkovich could handle since a sum of read-once formulae is always multilinear.
WebIn this paper we present a deterministic polynomial time algorithm for testing if a symbolic matrix in non-commuting variables over Q is invertible or not. The analogous question for … In mathematics, polynomial identity testing (PIT) is the problem of efficiently determining whether two multivariate polynomials are identical. More formally, a PIT algorithm is given an arithmetic circuit that computes a polynomial p in a field, and decides whether p is the zero polynomial. Determining the … See more The question "Does $${\displaystyle (x+y)(x-y)}$$ equal $${\displaystyle x^{2}-y^{2}\,?}$$" is a question about whether two polynomials are identical. As with any polynomial identity testing question, it can be trivially … See more • Applications of Schwartz–Zippel lemma See more • Lecture notes on "Polynomial Identity Testing by the Schwartz-Zippel Lemma" • Polynomial Identity Testing by Michael Forbes - MIT See more Given an arithmetic circuit that computes a polynomial in a field, determine whether the polynomial is equal to the zero polynomial (that is, the polynomial with no nonzero terms). See more In some cases, the specification of the arithmetic circuit is not given to the PIT solver, and the PIT solver can only input values into a "black box" that implements the circuit, and then analyze the output. Note that the solutions below assume that any operation (such … See more
