On Counting Mobile Lock Patterns

What are the chances Somebody will guess your Mobile pattern lock?

While I was teaching about probability in my Discrete Mathematics class, I came across this problem. I tried to solve it by counting all the simple paths in the graph. My approach was to systematically generate the paths leveraging the symmetry of grids and thus reduce almost 3/4 th of the computation. But I could not find an exact formulae to count them.

career

Lecturer

Undergraduate Course Instructor, Dept of CSE, Eastern University, 2019

I have taught 2 theory courses and 1 lab course which was in total 10.5 credit-hour/week.

CSE211: Discrete Mathematics (Lectured to a single class) (3 Credit)
I had encountered this problem while taking the class.
CSE103: Structured Programming (Lectured to a single class) (3 Credit)
It was an introductory course to programming for freshman year students. Taught the basics of programming with C language
CSE 104: Structured Programming Laboratory (Instructed 3 classes) (1.5*3 = 4.5 Credit)
It was the sessional part of CSE103 course. Here I got a chance to supervise projects of 40 very enthusiastic students.

Software Engineer

[Brief] I have worked on multiple system modules. My main contribution was in developing Samsung Cloud Service (system API) on Tizen 5.5 OS for Galaxy Watch3 models and later development in Android platform.

projects

Undergraduate Research

Developed an efficient computational tool on CPLM-2.0 database proposing a prediction scheme based on evolutionary conserved information of protein sequences. The study explored the efficacy of protein sequence based features and protein secondary structure for predicting Lysine Succinylation sites using machine learning techniques.
