Trait Implementations

impl<AccountId: IdentifierT, Accuracy: PerThing128, Balancing: Get<Option<BalancingConfig>>> NposSolver for SequentialPhragmen<AccountId, Accuracy, Balancing>

type AccountId = AccountId

The account identifier type of this solver.

type Accuracy = Accuracy

fn solve(
    winners: usize,
    targets: Vec<Self::AccountId>,
    voters: Vec<(Self::AccountId, VoteWeight, impl IntoIterator<Item = Self::AccountId>)>
) -> Result<ElectionResult<Self::AccountId, Self::Accuracy>, Self::Error>

Solve an NPoS solution with the given voters, targets, and select to_elect count of targets.

fn weight<T: WeightInfo>(voters: u32, targets: u32, vote_degree: u32) -> Weight

Measure the weight used in the calculation of the solver.
