Module 4: Graph Theory
Assignment: graph theory.
A spell checker in a word processing program makes suggestions when it finds a word not in the dictionary. To determine what words to suggest, it tries to find similar words. One measure of word similarity is the Levenshtein distance, which measures the number of substitutions, additions, or deletions that are required to change one word into another.
For example, the words spit and spot are a distance of 1 apart; changing spit to spot requires one substitution (i for o). Likewise, spit is distance 1 from pit since the change requires one deletion (the s). The word spite is also distance 1 from spit since it requires one addition (the e). The word soot is distance 2 from spit since two substitutions would be required.
a) Create a graph using words as vertices, and edges connecting words with a Levenshtein distance of 1. Use the misspelled word “moke” as the center, and try to find at least 10 connected dictionary words.
b) How might a spell checker use this graph?
Here’s some ideas on how to upload a graph:
- Draw it on paper, scan it into the computer, and upload it. If your file is too large to upload, you are welcome to email it to me instead.
- Draw it on paper, take a picture with your digital camera or cell phone camera and upload it. Please make sure it’s legible in the picture!
- Draw it in Paint or another computer drawing program and save it as a picture and upload it.
- In Word, use the drawing tools to create a graph, perhaps using Text Boxes and Lines. Save and upload
If you really can’t figure out a good way to digitally send your graph, you can physically drop it by my office.
Here is an example of this type of graph, using “rab” as the center. Pardon the quality; I drew it in Paint :)

Graph Theory is a branch of mathematics that is concerned with the study of relationships between different objects. A graph is a collection of various vertexes also known as nodes, and these nodes are connected with each other via edges. In this tutorial, we have covered all the topics of Graph Theory like characteristics, eulerian graphs, planar graphs, special graphs, trees, paths in graph theory, etc. This Graph theory tutorial will be helpful in learning the concept of the subject along with the applications of graph theory in real life and in various fields.

graph is a graph that does not contain any arrows on its edges, indicating which way to go. A directed graph, on the other hand, is a graph in which its edges contain arrows indicating which way to go. 2.2 Properties of graph In this section we will cover key properties of a graph. There are two main properties of a graph: degrees and walks.

Graph Theory Written Assignment By: Michelle Gray I've never heard of the Levenshtein Distance, and even though I don't understand how this applies to Graph Theory, I can visualize how this would apply to Spell Checker. It's almost like (in this case) "moke" is the heart and all the other words/lines are the veins sprouting from that heart.
