Modeling chutes and ladders as a Markov chain | Isaac Slavitt

http://isaacslavitt.com/2014/01/03/chutes-and-ladders-markov-chain

Modeling chutes and ladders as a Markov chain. Every month, the magazine ORMS Today. Features an Operations Research related puzzle called The PuzzlOR by John Toczek, available online here. I always find these pretty fun, and Octobers puzzle. Here was the question last month:. A player starts at the red Start square and finishes at the green Finish square. A player advances along the board by spinning a spinner that results in moving forward one to three squares. Given the rules of the game and the board...

On science, mathematics, and computing. The fourth-best for the job. Floating-point round trips revisited →. June 21, 2015. I often need to display or record output of floating-point values, in a human-readable decimal format. This is easy enough in most programming languages… unless you need the representation to be one-to-one. So that distinct finite values always produce distinct output. More precisely, we would like to be able to (1) convert a floating-point value. In C , you can set the precision.

Introduction Much of my work involves discrete event simulation, where a simulation advances, in discrete jumps, from one “interesting” point in time (called an event) to the next. Managing execution of such a simulation is pretty straightforward when everything happens … Continue reading →. Update: Chutes and Ladders is long, but not *that* long. March 11, 2015.

On science, mathematics, and computing. Update: Chutes and Ladders is long, but not *that* long →. Analysis of Chutes and Ladders. February 20, 2015. A friend of mine has been playing the board game Chutes and Ladders. Recently with his son. The game is pretty simple: starting off of the board (effectively on “square zero”), each player in turn rolls a die. Actually, spins a spinner) and– if possible– moves forward the indicated number of squares in serpentine fashion on the board shown below:. While sta...

On science, mathematics, and computing. August 24, 2016. Consider the following problem: given a value in the MATLAB programming language, can we serialize it into a sequence of bytes– suitable for, say, storage on disk– in a form that allows easy recovery of the exact original value?
