Enum PolynomialInputTransform 

pub enum PolynomialInputTransform {
    Identity,
    Square,
    SquareTimesInput,
    ChebyshevT2,
    ChebyshevT2TimesInput,
}

Input rewrite attached to a decomposed polynomial.

Polynomials with a known parity can be folded through x² (monomial basis) or T₂(x) = 2x² - 1 (Chebyshev basis), halving the encoded degree. Odd polynomials additionally factor out one copy of the original input.

Variants

Identity

Evaluate the encoded polynomial directly on the input.

Square

Evaluate the encoded polynomial on x².

SquareTimesInput

Evaluate the encoded polynomial on x², then multiply by x.

ChebyshevT2

Evaluate the encoded polynomial on T₂(x).

ChebyshevT2TimesInput

Evaluate the encoded polynomial on T₂(x), then multiply by x.
