An alternative algorithm called Breath-First search provides us with the ability to return the same results as DFS but with the added guarantee to return the shortest-path first. This algorithm is a little more tricky to implement in a recursive manner instead using the queue data-structure, as...
In graph theory, the complement of a graph G is a graph H on the same vertices such that two distinct vertices of H are adjacent if and only if they are not adjacent in G. Now you are given an undirected graph G of N nodes and M bidirectional edges of unit length. Consider the co...

If we reach the specified end node, we terminate the algorithm and report success. If we reach a node with only neighbors we’ve already seen or no neighbors at all, we go back one step and try one of the neighbors we didn’t try last time. The only difference between DFS and BFS ...
algorithm design within this space is the problem of checking for the existence or (shortest) path between two or more vertices in the graph. Properties such as edge weighting and direction are two such factors that the algorithm designer can take into consideration. In this post I will be ...
On External Memory Graph Traversal We describe a new external memory data structure, the buffered repository tree, and use it to provide the first non-trivial external memory algorithm for directed breadth-first search (BFS) and an improved external algorithm for directed... AL Buchsbaum,M ...

You have agraph GwithV verticesandE edges. The graph is a weighted graph but the weights have a contraint that they can only be 0 or 1. Write an efficient code to calculate shortest path from a given source. Solution : Naive Solution — Dijkstra's Algorithm. ...
