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. 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.
