Fuzzy Mathematics with FuzzPy (Part 2) 4 Nov 2010 | 12:00 am
In the first part of this post, we explored the foundations of fuzzy sets and fuzzy graphs, and discussed how you can use FuzzPy, a general fuzzy mathematics library for python, to work with these typ...
Fuzzy Mathematics with FuzzPy (Part 1) 18 Oct 2010 | 10:43 am
FuzzPy is a python library that exposes specialized datatypes to deal with a wide range of fuzzy number types, fuzzy sets, and fuzzy graphs. Binary operations against each type, such as set unions and...
Algorithms in Python: Binary exponentiation 8 Aug 2010 | 03:10 pm
The typical approach to exponentiation of a base b by an exponent n is to repeatedly multiply the base by itself, as such: This is easy to compute for small values but quickly chokes with very large ...
Algorithms in Python: Binary Operations 18 Jul 2010 | 07:08 am
Today I’d like to demonstrate a simple implementation of Kenneth Rosen‘s binary addition and multiplication algorithms as outlined in "Discrete Mathematics and its Applications". Both algorithms are v...
Algorithms in Python: Base Expansion 11 Jul 2010 | 12:53 pm
I felt it would be helpful to folks interested in Python and studying algorithms, to review some commonly studied algorithms in Computer Science by providing a small description and a Python implement...
Django Context Processors Best Practice 8 Apr 2010 | 12:59 pm
In this post, i’ll show you a simple trick to ensure your Django context-processors don’t break when Django 1.2 (and possibly future releases as well) is released. If you’re not familiar with the con...
