If by any chance Bell is wrong about his derivation of the inequalities for EPR-Bohm type experiments it should be demonstrable using a computer simulation. This blog is an attempt to discuss the possibilities and provide easy access to such local realistic models.

Allowing everyone to verify the models
Using a relative heavy IDE (Integrated Development Environment) like the free Visual Studio Express version for running the Monte Carlo - type simulations discussed in this blog makes it possible for everyone with a (Windows) computer to verify these models. A nice feature is the debugging possibility. This allows even those interested but with less programming experience to follow the code line by line while running, and inspecting the values in each calculation on the job. Of course this is essential in any attempt to prove Bell wrong by a simulation. With Visual Studio one just has to use the following steps:
Download the model(s) discussed fromSourceForce and unzip the zip-archive
Start VS2010 C# express
Use File, Open Project to open the solution file EPR_Bohm.sln
Start the simulation by pressing F5
After a short compilation time the program will show the main window that can be used for running a simulation.
Debugging For following the logic of the model, one just has to open a relevant file from the Project Explorer window, like Calc_Epr.cs, and click in the left (grey) margin to set a breakpoint. Whenever the line with the breakpoint is executed, the program halts at that point (1). Then, by right-clicking the objects used in that part of code, their current contents can be inspected . Even more, one can follow the execution of the program line by line by using the Step Into, Step Over and Step Out buttons (2).
