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. WebJun 10, 2024 · We look at the problem of blackbox polynomial identity testing (PIT) for the model of read-once oblivious algebraic branching programs (ROABP), where the number of variables is logarithmic to the input size of ROABP. ...

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). 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 … cylindrical motion

WebSchwartz–Zippel lemma. In mathematics, the Schwartz–Zippel lemma (also called the DeMillo–Lipton–Schwartz–Zippel lemma) is a tool commonly used in probabilistic … Webdeterminant polynomial (on dn dnmatrices). The alert reader will have noticed that in the commutative PIT problem, singularity is captured by a single polynomial identity, namely the case d= 1 above! Somehow, testing if a given tuple of matrices satisfies the infinite system of identities above seems now easier than testing the single one ... WebThere are some specific problems not known to be in P or NPC.Some examples:Polynomial Identity Testing,Graph Isomorphism,Factoring,DiscreteLog. One can also define NEXP,languages decidable in exponential time on a nondeterministic Turing machine.This class is of course very large.Inside the smaller class PSPACE,people … cylindrical mounts
