AggregateBits aggregates fees of the bits that agree on all the RemainingVotes.

BranchAndBoundBits takes a set of aggregated votes and a list of aggregated bits and tries to get an optimal subset of votes with the weight more than the half of the total weight.

BranchAndBoundBitsDouble runs two branch and bound strategies on bits in parallel and returns the better result.

BranchAndBoundVotes is similar to BranchAndBound, the difference is that it executes a branch and bound strategy on the space of subsets of bitVotes, hence it is particularly useful when there are not too many distinct bitVotes.

BranchAndBoundVotesDouble runs two branch and bound strategies on votes in parallel and returns the better result.

DecodeBitVoteBytes decodes bytes encoded BitVote.

earlierTx compares IndexTxs a,b.

Filter identifies the bits and votes that are guaranteed to be included in the selection of the consensus bitVote.
