Assignment 15 - Networks




Use overall knowledge of data structures to solve problems




In programming you are often confronted with a choice of choosing the correct object, structure, or algorithm to solve a problem. Making the wrong choice often leads to inefficiencies that must be corrected later or a complete inability to solve the problem.  This is important enough that there are even guides to technical interviews that help you get ready for these types of questions ( see http://careerdrill.com/blog/coding-interview/choosing-the-right-data-structure-to-solve-problems/ ). 


Also common in programming is the use of Caffeine (  https://en.wikipedia.org/wiki/Caffeine )





So you will get to have a little fun with this assignment. You will model a caffeine molecule as a graph and present that computer model. Edges that are single bonds should be presented with a weight of 1, with a double bond - they should have a weight of 2. 


Build your model as a Graph.  The graph should be able to print all of its Nodes with each adjacent node. You can have a print button or simply call it when the Graph is built.



H (C)  <- there will be 9 of these

C (N,H) <- there will be 3 of these

N (C, C, C) <- there are 3 of these

N (C, C) <- only one of these



for each element and combination of connected element



For added fun use the code at https://bl.ocks.org/mbostock/3037015  to make a graphical representation of the molecule. Special thanks to Amanda Krummel for modeling Caffeine using the graph associated with this block. While you are at it - take a look at blocks and see some of the things you will learn to do in the next class COP4813 http://cop4813eaglin.pbworks.com/w/page/34415594/FrontPage   (  https://bl.ocks.org/   )
