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.
