Deterministic polynomial identity testing
Webmials reduces to the problem of deterministic polynomial identity testing. Speci cally, we show that given an arithmetic circuit (either explicitly or via black-box access) that … WebIn the process, they must show that the relevant decision problem belongs in NP (section 2.5 on page 6). To do this, they describe an algorithm that nondeterministically solves …

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). WebWe 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]). A …
WebNamely, we show that in any model that is closed under partial derivatives (that is, a partial derivative of a polynomial computed by a circuit in the model, can also be computed by a circuit in the model) and that has an efficient deterministic polynomial identity testing algorithm, we can also answer the read-once testing problem. Webcomplexity of any polynomial in our model, and use it to prove exponential lower bounds for explicit polynomials such as the determinant. Finally, we give a white-box deterministic polynomial-time algorithm for polynomial identity testing (PIT) on unambiguous circuits over R and C. 1 Introduction

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. sharif couture handbags usedWebdeterministically, given a deterministic algorithm for the polynomial identity testing problem (we require either a white-box or a black-box algorithm, depending on the representation of f).
