Has anyone used a simulation library before? Which one do you think is the best?

What is a simulation library?

It's a C++ library which encompasses all the features we discussed above.

I found one of them on my hard drive, which is called C++ Sim,

But I think I have to give it up, because it is written for unix, not win32

which is the platform I am currently working on.

Sorry, I forgot to link to share. But it's from the University of NewCastle, UK

Wouldn't it just be easier to, at load time of the data you have, add/subtract a random number so that at load time you already have "randomized" data and act deterministically from there?

If you want to repeat the process several times, keep a copy of the original data, and recalculate the next time (with some randomness) a truck should go everytime a new truck goes.
