Function Documentation

◆ bfs()

BfsWizard<BfsWizardBase<GR> > lemon::bfs ( const GR &  digraph)

Function-type interface for BFS algorithm.

This function also has several named parameters, they are declared as the members of class BfsWizard. The following examples show how to use these parameters.

// Compute shortest path from node s to each node
bfs(g).predMap(preds).distMap(dists).run(s);
// Compute shortest path from s to t
bool reached = bfs(g).path(p).dist(d).run(s,t);
BfsWizard< BfsWizardBase< GR > > bfs(const GR &digraph)
Function-type interface for BFS algorithm.
Definition: bfs.h:1191
Warning
Don't forget to put the run() to the end of the parameter list.

◆ dfs()

DfsWizard<DfsWizardBase<GR> > lemon::dfs ( const GR &  digraph)

Function-type interface for DFS algorithm.

This function also has several named parameters, they are declared as the members of class DfsWizard. The following examples show how to use these parameters.

// Compute the DFS tree
dfs(g).predMap(preds).distMap(dists).run(s);
// Compute the DFS path from s to t
bool reached = dfs(g).path(p).dist(d).run(s,t);
DfsWizard< DfsWizardBase< GR > > dfs(const GR &digraph)
Function-type interface for DFS algorithm.
Definition: dfs.h:1121
Warning
Don't forget to put the run() to the end of the parameter list.
