Struct MultilinearQuery

source
pub struct MultilinearQuery<P, Data>
where P: PackedField, Data: DerefMut<Target = [P]>,
{ /* private fields */ }
Expand description

Tensor product expansion of sumcheck round challenges.

Stores the tensor product expansion $\bigotimes_{i = 0}^{n - 1} (1 - r_i, r_i)$ when round() is n for the sequence of sumcheck challenges $(r_0, …, r_{n-1})$. The tensor product can be updated with a new round challenge in linear time. This is used in the first several rounds of the sumcheck prover for small-field polynomials, before it becomes more efficient to switch over to the method that store folded multilinears.
