Computer simulations play an important role in many scientific and engineering problems. Depending on the given tasks, different methods are used: someone needs to solve complicated systems of equations which cannot be solved analytically, other perform numerous computations to get enough statistics without real-life experiments. The first mentioned group of tasks is often related to calculations on electric and electronic devices while the latter is often related to the statistics problems (a lot of problems in economy, thermodynamics, etc.). In this article, we discuss an example of how a simple analysis can be performed by the accumulation of the enough number of random events. (more…)
