Monaco - A program to determine probabilities, especially in dice and card games


Over the last few years I have created, for my own use, a program I call Monaco. Its purpose is to determine some probabilities, especially in dice and card games. Note that, despite that the name Monaco suggests approximate answers through Monte Carlo simulation, exact answers to many problems are also available, often very quickly. A recently added capability can provide results from processes that transition between states in a regular pattern, known as Markov chains.

It is possible that there may be others who would be interested in the program. So I have created a presentation (also available as PowerPoint) that provides an introduction, and a tutorial for the program. A followup second tutorial is also available. In addition I also have another document that describes how the program can be used to solve, or at least illustrate, some non-games probability problems that have been collected from various sources - although not by me. There is also some more detailed documentation, but I do not include it here.

If interested after seeing those (which may well prove to many people that they are not interested after all) then drop me a line at the address below and I can let you have a copy, together with the full documentation.
