Today marks the start of the fourth week. We are beginning the "Professional Design and Optimization" series! In a math test, if you see the same equation you just solved, it's a bit of a waste to ...

1. Introduction: Why is your program slow? Have you ever felt stressed waiting for a program to finish running? That slowness might actually be caused by "repeating the same calculations over and over ...

Abstract: Memoization is a computational technique for speeding up the complexity of computer algorithms. It stores the previously calculated results and invokes them later in the body of the ...

Note that functions are assumed to be unchanged as long as the name is unchanged. Redefined function (with decorator applied again) will return cached result of similar call to the original function.

Perhaps you know about functools.lru_cache in Python 3, and you may be wondering why we are reinventing the wheel. Well, actually not. This lib is based on functools. Please find below the comparison ...

Python trades runtime speed for programmer convenience, and most of the time it’s a good tradeoff. One doesn’t typically need the raw speed of C for most workaday applications. And when you need to ...
