WebThe reasons are fairly similar to the analysis of our depth-first traversal. The reason we say O instead of Θ is that not all of the vertices may be connected to the start vertex, so we may not end up traversing the whole graph. Considering the memory usage of breadth-first traversal leads to a similar result as a depth-first traversal.
