Implementations

impl MinimumCostFlowSolver

pub fn new(n: usize) -> Self

pub fn add_edge(&mut self, from: usize, to: usize, capacity: i64, cost: i64)

pub fn solve(&mut self, source: usize, sink: usize, flow: i64) -> Option<i64>

Find the minimum cost to send flow through a flow network from source to sink.

pub fn neg_solve(&mut self, source: usize, sink: usize, flow: i64) -> Option<i64>

Find the minimum cost to send flow through a flow network, which contains edges of negative cost, from source to sink.
