Functions
static util::Result< SelectionResult >	wallet::ErrorMaxWeightExceeded ()
util::Result< SelectionResult >	wallet::SelectCoinsBnB (std::vector< OutputGroup > &utxo_pool, const CAmount &selection_target, const CAmount &cost_of_change, int max_selection_weight)
util::Result< SelectionResult >	wallet::CoinGrinder (std::vector< OutputGroup > &utxo_pool, const CAmount &selection_target, CAmount change_target, int max_selection_weight)
util::Result< SelectionResult >	wallet::SelectCoinsSRD (const std::vector< OutputGroup > &utxo_pool, CAmount target_value, CAmount change_fee, FastRandomContext &rng, int max_selection_weight)
	Select coins by Single Random Draw (SRD).
static void	wallet::ApproximateBestSubset (FastRandomContext &insecure_rand, const std::vector< OutputGroup > &groups, const CAmount &nTotalLower, const CAmount &nTargetValue, std::vector< char > &vfBest, CAmount &nBest, int max_selection_weight, int iterations=1000)
	Find a subset of the OutputGroups that is at least as large as, but as close as possible to, the target amount; solve subset sum.
util::Result< SelectionResult >	wallet::KnapsackSolver (std::vector< OutputGroup > &groups, const CAmount &nTargetValue, CAmount change_target, FastRandomContext &rng, int max_selection_weight)
CAmount	wallet::GenerateChangeTarget (CAmount payment_value, CAmount change_fee, FastRandomContext &rng)
	Choose a random change target for each transaction to make it harder to fingerprint the Core wallet based on the change output values of transactions it creates.
std::string	wallet::GetAlgorithmName (const SelectionAlgorithm algo)
