accumulate()

template<typename FF_ >

template<typename ContainerOverSubrelations , typename AllEntities , typename Parameters >

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

inlinestatic

Expression for the generalized permutation sort gate.

The relation is defined as C(in(X)...) = q_delta_range * \sum{ i = [0, 3]} \alpha^i D_i(D_i - 1)(D_i - 2)(D_i - 3) where D_0 = w_2 - w_1 D_1 = w_3 - w_2 D_2 = w_4 - w_3 D_3 = w_1_shift - w_4

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.
