feat: Protogalaxy Combiner by codygunton · Pull Request #2436 · AztecProtocol/aztec-packages

codygunton · 2023-09-20T16:26:54Z

This work introduces the Protogalaxy combiner polynomial ($G$ in the paper). I reuse structures from our sumcheck code, and also try to reflect the sumcheck code's organization, as much as possible. The main result is a test file that tests the combiner construction in three special cases, touching on 2- and 4-instance folding.

Major points

Generalize tuple of tuples containers to Protogalaxy, where they need to handle a varying number of instances.
Introduce compute_combiner function.

Minor points

Move extend and evaluate out of BarycentricData and into Univariate for convenience.
Move shared sumcheck functions (e.g. for operating on tuples of tuples) into a utilities class.
Add get_random method to RelationParameters.

-    using TupleOfArraysOfValues = decltype(create_relation_values_container<FF, Relations>());
+    using SumcheckTupleOfTuplesOfUnivariates = decltype(create_sumcheck_tuple_of_tuples_of_univariates<Relations>());
+    using SumcheckTupleOfArraysOfValues = decltype(create_sumcheck_tuple_of_arrays_of_values<Relations>());



these are much clear names to me, also thanks for the comments :)

    /**

+     * @brief A container for univariates used during Protogalaxy folding and sumcheck.


we should probably have no mention of ProtoGalaxy in here since we are not going to fold ECC VM

                                 proof_system::AuxiliaryRelation<FF>>;

    static constexpr size_t MAX_RELATION_LENGTH = get_max_relation_length<Relations>();
+    static_assert(MAX_RELATION_LENGTH == 6);


why is there a static_assert only here?

Oh this was just me checking what I thought was true. Will remove.

maybe one sentence explainer of what these univariates are? here and in the other flavors

maramihali · 2023-10-17T11:27:16Z


 template <typename Flavor_, size_t NUM_> struct ProverInstances_ {
    using Flavor = Flavor_;
+    using FF = typename Flavor_::FF;


is this preferred to Flavor::FF?

No there's no difference

can you pleasea define what num-identities is here?

I didn't write this but I added a clarification

maramihali · 2023-10-17T12:01:07Z

+ * @brief Recursive utility function to construct a container for the subrelation accumulators of Protogalaxy folding.

worth giving the mathematical formula here to make it more clear

IMO more detail than we should give here. Very easy to find the function that computes this.

maramihali · 2023-10-17T13:37:12Z

+template <typename Flavor>
+std::pair<std::array<barretenberg::Polynomial<typename Flavor::FF>, Flavor::NUM_ALL_ENTITIES>,
+          typename Flavor::ProverPolynomials>
+get_sequential_prover_polynomials(const size_t log_circuit_size, const size_t starting_value)


can you briefly document this?

maramihali · 2023-10-17T13:39:57Z

    using FF = typename Flavor::FF;
-    template <size_t univariate_length>
-    using ExtendedEdges = typename Flavor::template ExtendedEdges<univariate_length>;
+    using ExtendedEdges = typename Flavor::ExtendedEdges;


formatting weirdness?

No, MAX_RELATION_LENGTH is computed at compile time. This didn't need to be a template.

maramihali · 2023-10-17T14:03:29Z

+using FF = typename Flavor::FF;
+using RelationParameters = proof_system::RelationParameters<FF>;

CombinerOnTwoInstances maybe? ditto on the other test
