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. 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. minimum wages law in india https://jrwebsterhouse.com
