WebA maximum linear matroid parity set is called a basic matroid parity set, if its size is the rank of the matroid. We show that determining the existence of a common base (basic matroid parity set) for linear matroid intersection (linear matroid parity) is in NC2, provided that there are polynomial number of common bases (basic matroid parity sets). WebThere exists a deterministic polynomial identity testing algorithm for multilinear formulae that runs in time sO(1)·nkO(k), where s denotes the size of the formula, n the number of variables, and k the maximum number of times a variable appears in the formula. There also exists a deterministic blackbox algorithm
Web4. We give new PIT algorithms for ∑Π∑ circuits with a bounded top fan-in: (a) A deterministic algorithm that runs in quasi polynomial time. (b) A randomized algorithm that runs in polynomial time and uses only polylogarithmic number of random bits. Moreover, when the circuit is multilinear our deterministic algorithm runs in polynomial time. WebSchwartz–Zippel lemma. In mathematics, the Schwartz–Zippel lemma (also called the DeMillo–Lipton–Schwartz–Zippel lemma) is a tool commonly used in probabilistic …
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.

WebDevising an efficient deterministic – or even a non-deterministic sub-exponential time – algorithm for testing polynomial identities is a fundamental problem in alge-braic complexity and complexity at large. Motivated by this problem, as well as by results from proof complexity, we investigate the complexity of proving polynomial identities. grants for carers walesWebWe also give a deterministic polynomial time algorithm for identity testing for, so called, pure set-multilinear arithmetic circuits (first defined by Nisan and Wigderson [4]).
