Assignment Help:
Objective

The goal of this project is to extend and implement an algorithm presented in the course and to apply notions introduced by the course to this program/algorithm. The assignment is relatively open-ended. The instructor will answer any question you may have. However, when in doubt, work toward the project goal stated above. This is an individual project. You may discuss it with other students, but the work you present must be your own only.

Deliverable

You will produce two items: (1) the code of the program specified below, and (2) a narrative of your work specified below. You will e-mail both items to the TA (whose address will become available in the syllabus early in the course). The items will be transmitted as attachments to your e-mail. The code will be formatted as ASCII text. The narrative will be formatted as either ASCII text or PDF. The deadline follows the rules of the homework, the beginning of the first lecture of the week following the assignment, except that you will e-mail the material rather than bringing a hard copy to class. Late submission will be accepted up to 3 days and will be penalized at 10% a day.

Code spec

Your code will extend and implement the Knapsack Problem as presented in Section 8.2 of the textbook. The extension will become clear while describing the output. Your program is expected to read a file called "input-2.txt" containing 3*k lines, li,j for i in 1,2,... k and j in 1,2,3. An example of input file is input-2.txt. For any i, line li,1 contains n positive integers separated by a comma. They are the weights W1,W2,... of a Knapsack Problem instance with n items, where n is less than 100. Likewise, line li,2 contains n positive integers separated by a comma. They are the values V1,V2,... of the items whose weights are in the previous line. Finally, line li,3 contains a single integer, the knapsack capacity. No other characters beside digits and commas are in each line.

Your program is expected to write a file called "output-2.txt" containing 5*k lines, mi,j for i in 1,2,... k and j in 1,2,...5. The output file corresponding to input-2.txt is output-2.txt. For i in 1,2,... k and j in 1,2,3, mi,j=li,j. Line mi,4 contains a single integer, the Knapsack Problem instance optimal solution. Line mi,5 contains a sequence of positive integers in increasing values. They are the indexes, starting with 1, of the items that make up an optimal solution. The general format of the output is the same as the format of the input. The extension with respect to the textbook algorithm is the generation of a set of items witnessing an optimal solution. If there is more than one set, any set is acceptable.
The weights, values, capacities and other parameters will be within reasonable ranges for a modern laptop or desktop. The programming language can be any of Java, Python, Ruby, C, and C++. Deliver all your code in a single file that can be compiled and executed on cs.pdx.edu. Your program should perform reasonably efficiently both in theory and in practice.

Narrative spec

The narrative is intended to show that you know and understand the aspects of the project related to this course, in particular, ability to: (1) extend and implement an algorithms, (2) relate theoretical complexity to practice, (3) code correct, readable and efficient programs, and (4) communicate your work clearly and concisely.

I would expect to find one or more of the following: (1) a description of the extension in the same style as the algorithm in the textbook, (2) a description of key data structures and algorithms used in the program, (3) the running time analysis of your algorithm/program, and (4) any benchmarking, profiling and/or testing employed for development.

Hints

You are encouraged to start your work early. Reading and writing the files are tasks that you already partially solved in Project 1. The Knapsack Problem is very easy to understand. Initially, you can implement a brute force program without computing the indexes. This will work for small problem instances. Then, you can replace the brute force approach with the dynamic programming approach presented in the textbook. Finally, you can introduce the extension. As the code evolves, you can use the previous version to test the current version''s correctness.
