Algorithm analysis – Big O notation
Continuing from my previous post on performance analysis of algoritms, I decided to plot the CPU-time over the size of the problem, that is, the number of cells. The two graphs above, both plotted ‘log-log’, demonstrate a straight line. A straight … Continue reading
Single simulation run consuming 230 h (!) of cpu-time – root cause analysis of performance
I think I’ve broken some kind of record of CPU-time consumption for a single simulation run… for a fairly trivial application… As my frequent readers know, I’ve been playing lately with a simulation of Shelling’s segration model (see previous posts … Continue reading

Animation of Thomas Shelling’s Segregation model
Programmed in Python, NumPy, SciPy and Prof. John Zelle’s Graphics Library
Graphics programming with Python
For reasons unknown to me, probably psychological, I’ve always hated graphics programming…. Never touched it, if I could avoid it… Over the past 40 years that I’ve been programming,professionally as well as privately, most of the time making ‘the pedal … Continue reading
Schelling’s segration model: evolution
The image above shows the evolution, per iteration, for a run of the Schelling simulation. The upper left grid shows the initial condition, which is a randomly arranged state. The seven remaining grids show the state of the board after … Continue reading
There’s a bug in my program: The enormous difference between < and <=
I’ve found a bug in my program! A bug, in my program…! And I’m a pro hacker, how shameful…! 🙂 Scary, isn’t it… a simple bug, a single character among the thousands of characters in my program… that single character … Continue reading
Segregation – technical details
Just a few details to the more technically inclined readers of this blog: The image below has three sections: the leftmost showing the results in terms of where the agents prefer to be, the middle image showing a heatmap over … Continue reading
Segration demo by computational agent simulation
For the fun of it, (and to learn more about Numpy’s multidimensional arrays) I decided to repeat Thomas Shelling’s famous experiment which demonstrates that segregation based on any real or imagined divider, such as gender, income, language,age, ethnicity, race, social status, … Continue reading
Surrounded by average people… what’s the likely IQ of your neighbour…?
IQ, the intelligence quotient, is defined as a normal distribution with mean of 100, and a standard deviation of 15. According to James Flynn, people with IQ 70 or less, are mentally retarded, while those with IQ 130 or more, … Continue reading
Probability Distributions for Dummies – Drunken walks and blindfolded archers
After having spent a few evenings exploring Python’s various math & science modules, specifically those dealing with probability, simulation and statistics, perhaps it’s time for a brief summary. In my previous recent posts, I’ve gone thru concepts such as mild … Continue reading
