Deterministic polynomial identity testing

WebAug 2, 2016 · A read-once oblivious arithmetic branching program (ROABP) is an arithmetic branching program (ABP) where each variable occurs in at most one layer. We give the first polynomial-time whitebox identity test for a polynomial computed by a sum of constantly many ROABPs. We also give a corresponding blackbox algorithm with quasi-polynomial … Webno deterministic counterpart to this randomized procedure. In fact, nding a deterministic algorithm for polynomial identity testing would lead to many interesting results, with impact akin to P=NP [KI04]. Before jumping to the full proof of the Schwartz-Zippel Lemma, let’s rst prove a simpler instance. 1.2 Matrix Identity Testing

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. 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.
