static void bb::EccOpQueueRelationImpl< FF_ >::accumulate ( ContainerOverSubrelations &  accumulators, const AllEntities &  in, const Parameters &  , const FF &  scaling_factor  )

Expression for the generalized permutation sort gate.

The relation is defined as C(in(X)...) = \alpha_{base} * ( \Sum_{i=0}^3 \alpha^i * (w_i_shift - w_{op,i}) * \chi_{ecc_op} + \Sum_{i=0}^3 \alpha^{i+4} w_{op,i} * \bar{\chi}_{ecc_op} )

where w_{op,i} are the ecc op gate wires, \chi_{ecc_op} is the indicator for the portion of the domain representing ecc op gates and \bar{\chi} is the indicator on the complementary domain.

The first four sub-relations check that the values in the conventional wires are identical to the values in the ecc op wires over the portion of the execution trace representing ECC op queue gates. The next four check that the op wire polynomials are identically zero everywhere else.

Note

This relation utilizes the shifted wires so that the ecc op wires can store the data begining at index 0, unlike the wires which contain an initial zero row to facilitate the left-shift-by-1 needed by other relations.

Parameters

evals	transformed to evals + C(in(X)...)*scaling_factor
in	an std::array containing the fully extended Univariate edges.
parameters	contains beta, gamma, and public_input_delta, ....
scaling_factor	optional term to scale the evaluation before adding to evals.
