MATH36031 Problem solving by computer

Project 1 – deadline 27th October 2023, time 1100hrs. Submission of the project is via Blackboard.
In the tasks required for this project you are asked to use an algorithm which originates from the Vedic system of mathematics developed in India several hundred years ago. The algorithm is described in the video clip which is available via Blackboard in the Projects folder.

Project Tasks

Write a function myrandi $(\mathrm{n})$ which takes as input a positive integer $\mathrm{n}$ and generates as output a string $a_1, a_2, \ldots, a_n$ containing the digits of a positive number $a_1 a_2 \ldots a_n$. Here the $a_k$ are random integers $0 \leq a_k \leq 9$.

Watch the video clip to learn about the algorithm used to multiply two numbers. In the video clip, the algorithm is described for multiplication of numbers up to 5 digits long. Your task is to generalise the algorithm to work out the patterns to multiply two $n$ digit numbers. In your report you should describe and explain how this algorithm works.

Write a function vedicmultiply to implement this algorithm and such that $\mathrm{c}=$ vedicmultiply $(\mathrm{a}, \mathrm{b})$ returns a string $\mathrm{c}$ which contains all the digits of the multiplication of $\mathrm{a}$ and $\mathrm{b}$ (which are input as a string). Also the integers represented by $a$ and $b$ can have a different number of digits. In your report you should explain and provide details of any testing and validation that you have done.

Example c=vedicmultiply (’12’, ’34’) returns c=’ 408 ‘.

function [nyans] - vedicmultiply (a,b)
\%vedicmultiply computes the product a+b
\% vedcimultiply computes the product of the numbers $a+b$ where
$\mathrm{X}$ a and $\mathrm{b}$ are input $8 \mathrm{~s}$ strings (to allow for long integers)
usage: a='12345'; b-'123' c=vedicmultiply (a,b)
myans is a list containing all the digits of the ansuer

Use your myrandi and vedicmultiply functions to give all the digits in the multiplication of two randomly-chosen random positive numbers $\mathrm{a}$ and $\mathrm{b}$ where $\mathrm{a}$ is of length 30 and $\mathrm{b}$ is of length 40 . The full output (showing all the digits) should be given in your report.

Produce a clearly labelled plot showing $N$, the number of digits in the integer along the $x$-axis versus $T$ the average time to do 100 multiplications using two positive random integers each with $N$ digits, on the $y$-axis. Ideally take $N=10: 10: 50$.

Course description

This flexible single-honours undergraduate Masters degree programme offers you the widest choice of options, ideal if you are mathematically gifted and wish to keep your options open. You get good all-round mathematical knowledge together with the ability to experience more specialised results, methods, and ideas. You can choose courses from other disciplines and from a huge variety of mathematics options allowing you to graduate with finely-honed skills in your own chosen areas. You get an education in sufficient depth in these specialised areas to enable you to undertake postgraduate studies, conduct mathematical research or work as a specialist mathematician in industry, business, or higher education.

Additional Information

• All coding must be done in MATLAB and you are required to submit your MATLAB functions and $\mathrm{m}$ (or $\mathrm{mlx}$ )-files via the Blackboard submission box. Project reports in pdf form only should be submitted via the Turnitin submission box. Remember the Turnitin software will automatically scan reports for plagiarism.
• Please ask if you need help on any commands, or whether there are built-in command$\mathrm{s} /$ functions to accomplish certain tasks (especially important if you think you have a good approach to the questions, but do not know the related commands).
• The default datatype is double (decimal number), and be aware of possible side effects when using the numbers as integers. Remember that the same question can be solved by different approaches, and the same approach can be implemented in different ways. All relevant commands should be covered during the lectures or tutorial exercises, but you are free to explore your own. Make critical judgement to choose the best approach/implementation.
• Aim for efficiency of the code, which is an additional marking criteria, besides the generic rubric. Although you only need to record the answer for the given input, make sure that the computational time or memory does not increase significantly with larger input parameters (these issues will be mentioned constantly during the class demonstrations).
• List the complete code of the whole code for solving the tasks at the end of each question, or in an appendix. Make your source code more readable, by keeping the indentation and stylistic features, and can be copied from the electronic file.
• The results reported in your report must be reproducible from your codes. Remember that markers will be able to run the codes in case of any doubts and any inconsistencies between reported results and actual results from running codes will lead to reports being marked down.
