This post is slightly psychology influenced. Well, in the Psychology class I have been taking this semester (Introduction To Cognitive Learning), I was taught about Neural Networks and a certain Hebb’s Rule which allows a network to remember a previous configuration and use this configuration to interpret new information. We use the following model to [...]

While suffering from conjuctivitis, fever, a sore throat and what seems to be a case of swollen tonsils determined to make nutrition a pain for the next week or two, I decided to solve a problem on Project Euler. The question I picked was Problem 33: Find all fractions with the given unorthodox cancelling method [...]

I had the opportunity to work on an interesting problem:
Find a decent approximation for the Zeta function (large values), given by:
So, to make any sort of headway, I decided that I would have to look at the graph. Hence, I whipped up a script in Python:

Here is the first bit of code I’ve ever written at college (on my own computer though, I’ve concentration problems in the lab). I was solving problem 39 of the project euler problem set (and I am ashamed of my work). So the question is:
If p is the perimeter of a right angle triangle with [...]

Factoradic
August 13th, 2008 · 2 Comments · Mathematics, python
I was trying to solve the lexicographic permutation problem yesterday and out of plain curiosity, I decided to carry out some research on Wikipedia. I found this thing called factoradic which is a factorial-based number system. I conveniently used this thing to approach the solution and decided to work out how factoradic actually worked.
I decided [...]

In the past week, I have traveled across 4 major pilgrimage centers and of course accumulated lots of brownie points for no stupid comments on the deities. I have decided to add more content to my site, mostly to make it humorous etc.
