Keep Marching On by Markov Walker
January 6th, 2010 8:49 PMTo keep things simple I'm using a stationary Markov chain to choose my path. The transition probabilities are presented below. The rows have the current state, while the columns have possible next states. Each cell is the probability of going to that next state (labeled at the top of the column) given that I'm in the current state (labeled at the beginning of the row), along with the range of numbers on a roll of a 10 sided die that would produce that result. Thus, the probabilities across each row sum to 1.
I start off in the garage. Notice that the bar is a stopping state, and the home and Target are like a choke points, dividing my day in two. The most probable path for the day is garage -> Casa -> Jewel -> home -> Target -> DePaul -> bar, with a probability of 0.08064.
The actual path I wound up traveling was garage -> Casa -> home -> coffee -> DePaul -> bar, with a path probability of .00336.
The rest of this story is told with the pictures.

my table and a the 10 sided die that decided how I'd go about my day.

I am in the garage at the beginning, ready to go.

The first roll sends me to La Casa Del Pueblo.

Arrived at La Casa. Now, all influence of starting at the garage on my future travels is destroyed. 
second roll (la casa).jpg
And the die sends me back home.

Back at home, the fact that I came from La Casa del Pueblo and never went to Jewel to get other groceries has no influence over future future movement.
third roll (home).jpg
The die sends me from home to coffee

So I seek efebos for my fix. And now the fact that I did not make my trip to Target to replace my roommate's broken French press has no influence on my future.

Inside efebos. I have a friend who doesn't like another coffee shop down the street because there are "too many hipsters" and prefers this place. The way I reckon, if you find yourself complaining about hipsters, chances are you are one.

My next roll sends me to depaul

I arrive at DePaul, destroying any influence that getting coffee might have over my future destinations. I still have a 1 in 5 chance of getting coffee as my next step, despite the fact that I just got coffee.
fifth roll (depaul).jpg
My last roll finally sends me to the bar for dollar burgers and $3 DTs.

Inside the bar. It sucks. There are TVs everywhere, even a TV right in our booth. Fortunately, we can turn the one in the booth off. But on Wednesday, they have awesome food and beer for cheap.

My company at this bar, and my only reason for putting DePaul on my destination table.

This is one of the most under appreciated praxis this era. This is clever and original and awesome once you wrap your head around it.
