In general, a graph may have several spanning trees, but a graph that is not connected will not contain a spanning tree (see about spanning forests below). If all of the edges of G are also edges of a spanning …
WebMar 15, 2012 · Depth-first search is an algorithm for traversing or searching tree or graph data structures.

The problem can be modelled as finding a negative-weight cycle in a graph. The nodes are the currencies, the edges are the exchange-rate pairs, and the edge weight is -log(r) for an exchange rate r .
