Function Documentation

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);

Warning

Don't forget to put the run() to the end of the parameter list.

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);

Warning

Don't forget to put the run() to the end of the parameter list.
