Representation of capacity and flow data.

Required methods

fn new(size: usize, source: usize, sink: usize) -> Self where
    Self: Sized, [src]

Create a new empty structure.

Panics

This function panics when source or sink is greater or equal than size.

fn from_matrix(source: usize, sink: usize, capacities: Matrix<C>) -> Self where
    Self: Sized, [src]

Create a new populated structure.

Panics

This function panics when source or sink is greater or equal than the number of rows in the capacities matrix, or it the matrix is not a square one.

fn common(&self) -> &Common<C>[src]

Common data.

fn common_mut(&mut self) -> &mut Common<C>[src]

Mutable common data.

fn residual_successors(&self, from: usize) -> Vec<(usize, C)>[src]

List of successors with positive residual capacity and this capacity.

fn residual_capacity(&self, from: usize, to: usize) -> C[src]

Residual capacity between two nodes.

fn flow(&self, from: usize, to: usize) -> C[src]

Flow between two nodes.

fn flows_from(&self, from: usize) -> Vec<usize>[src]

All positive flows starting from a node.

fn flows(&self) -> Vec<((usize, usize), C)>[src]

All flows between nodes.

fn add_flow(&mut self, from: usize, to: usize, capacity: C)[src]

Add a given flow between two nodes. This should not be used directly.

fn add_residual_capacity(&mut self, from: usize, to: usize, capacity: C)[src]

Add some residual capacity.

Provided methods

#[must_use]
fn from_vec(source: usize, sink: usize, capacities: Vec<C>) -> Self where
    Self: Sized, [src]

Create a new populated structure.

Panics

This function panics when source or sink is greater or equal than the number of rows in the square matrix created from the capacities vector.

fn size(&self) -> usize[src]

Number of nodes.

fn source(&self) -> usize[src]

Source.

fn sink(&self) -> usize[src]

Sink.

fn set_capacity(&mut self, from: usize, to: usize, capacity: C)[src]

Set capacity between two nodes.

fn total_capacity(&self) -> C[src]

Get total capacity.

fn set_total_capacity(&mut self, capacity: C)[src]

Set total capacity.

fn omit_detailed_flows(&mut self)[src]

Do not request the detailed flows as a result. The returned flows will be an empty vector.

fn detailed_flows(&self) -> bool[src]

Are detailed flows requested?

fn augment(&mut self) -> EKFlows<usize, C>[src]

Compute the maximum flow.

fn cancel_flow(&mut self, from: usize, to: usize, capacity: C)[src]

Internal: cancel a flow capacity between two nodes.
