Struct OptimizedArcMatrix

pub struct OptimizedArcMatrix<const N_ROWS: usize, const N_COLS: usize, const N_ELEMENTS: usize>(pub ArcMatrix<N_ROWS, N_COLS, N_ELEMENTS>);

Represents an optimized matrix of round constants.

This modifies the partial rounds in the middle of the permutation, wherein you add constants first before iterating through the partial rounds.

This method follows calc_equivalent_constants from Appendix B’s poseidonperm_x3_64_24_optimized.sage.
