Graph edit distance is a graph similarity measure analogous to Levenshtein distance for strings. It is defined as minimum cost of edit path (sequence of node and edge edit operations) transforming graph G1 to graph isomorphic to G2. Parameters: G1, G2 ( graphs) – The two graphs G1 and G2 must be of the same type.
Returns all minimum-cost edit paths transforming G1 to G2. Graph edit path is a sequence of node and edge edit operations transforming graph G1 to graph isomorphic to G2. Edit operations include substitutions, deletions, and insertions.

Edit Distance is quite a interesting and popular problem. Here I present an efficient bottom up C++ program to solve it. Problem - We are given 2 strings. We have to find the "edit distance" or the cost of converting one string to other. We are allowed 3 operations - Insert, Delete, Replace.

The use of graphs is widespread in computing. Many everyday and practical problems can be modelled on graphs. We'll start out by looking at how to construct and draw a few kinds of graphs and then discuss some fundamental algorithms we can use with them. To actually carry out the computations, we'll be using a Python module called NetworkX.

The diameter of a graph is the maximum eccentricity of any vertex in the graph. That is, is the greatest distance between any pair of vertices or, alternatively, = ∈ (). To find the diameter of a graph, first find the shortest path between each pair of vertices. The greatest length of any of these paths is the diameter of the graph.
