Fields

powers_of_g: BTreeMap<P::Term, E::G1Affine>

Contains group elements corresponding to all possible monomials with num_vars and maximum degree supported_degree evaluated at \beta

gamma_g: E::G1Affine

\gamma times the generater of G1

powers_of_gamma_g: Vec<Vec<E::G1Affine>>

Group elements of the form { \beta_i^j \gamma G }, where i ranges from 0 to num_vars-1 and j ranges from 1 to supported_degree+1.

num_vars: usize

The number of variables self is initialized for

supported_degree: usize

The maximum degree supported by the trimmed parameters that self is a part of

max_degree: usize

The maximum degree supported by the UniversalParams self was derived from.
