void bb::TranslatorAccumulatorTransferRelationImpl< FF >::accumulate ( ContainerOverSubrelations &  accumulators, const AllEntities &  in, const Parameters &  params, const FF &  scaling_factor  )

static

Relation enforcing non-arithmetic transitions of accumulator (value that is tracking the batched evaluation of polynomials in non-native field)

This relation enforces three pieces of logic: 1) Accumulator starts as zero before we start accumulating stuff 2) Accumulator limbs are propagated correctly from an odd row to the next even row 3) Accumulator limbs result in the values specified by relation parameters after accumulation

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.

static bool bb::TranslatorAccumulatorTransferRelationImpl< FF_ >::skip ( const AllEntities &  in )

inlinestatic

Returns true if the contribution from all subrelations for the provided inputs is identically zero.

This has a negligible chance of failing in sumcheck (not in the first round) because effectively transform original coefficients into a random linear combination. But checking each individually is noticeably slower.
