[−][src]Struct rs_graph::maxflow::pushrelabel::PushRelabel

pub struct PushRelabel<'a, G, F> where
    G: 'a + IndexDigraph<'a>,  {
    pub cnt_relabel: usize,
    pub use_global_relabelling: bool,
    // some fields omitted
}

The push-relabel algorithm.

This struct contains all algorithmic working data.

Fields

cnt_relabel: usize

The number of relabel operations performed during the algorithm.

use_global_relabelling: bool

Whether to use the global relabelling heuristic.

Trait Implementations

impl<'a, G, F> MaxFlow<'a> for PushRelabel<'a, G, F> where
    G: IndexDigraph<'a>,
    F: NumAssign + Ord + Copy, [src]

type Graph = G

Type of the underlying graph.

type Flow = F

Type of flows.

fn new(g: &'a G) -> Self[src]

Return a new push-relabel algorithm data structure for the digraph g.

fn as_graph(&self) -> &'a Self::Graph[src]

Return a reference to the underlying graph.

fn value(&self) -> F[src]

Return the flow value.

The function returns 0 if the flow has not been computed, yet.

fn flow(&self, e: G::Edge) -> F[src]

Return the flow value over some edge.

The function returns 0 if the flow has not been computed, yet.

fn solve<Us>(&mut self, src: G::Node, snk: G::Node, upper: Us) where
    Us: Fn(G::Edge) -> Self::Flow, [src]

Run the push-relabel algorithm from some source to some sink node.

fn mincut(&self) -> Vec<G::Node>[src]

Return the minimal cut.
