Because of the nature of the simulation, the results are not error-bound as they would be in a deterministic model. Monte Carlo integration addresses the dimensionality issue by multiplying the standard error of the mean with the volume of the space. However, Monte Carlo models are a broad, loosely-defined group of algorithms, and as such, some non-deterministic models exist, namely Monte Carlo integration, that are better suited to solving problems of higher dimensionality. In other words, it’s easy to come up with many real-world examples and problems that would quickly overwhelm the computational ability of a particular Monte Carlo simulation.
While this may seem conceptually difficult, most engineers are well-acquainted with higher dimensional spaces an individual dimension represents a degree of freedom for the system. That is to say, a Monte Carlo simulation that works computationally well in two- or three-dimensional space would be completely insufficient for twenty-dimensional space or beyond. The Monte Carlo method can have a significant drawback: an appropriately-sized data set climbs in exponential power alongside the dimensionality of the space. As with most computational algorithms, the confidence of the method’s solution rapidly climbs with more data. The approach functions best with a probability distribution that provides uniform scattering over the space as well as a large number of data points. The Monte Carlo method is a computational algorithm that attempts to solve problems, potentially deterministically, with the use of a random or pseudorandom dataset over some defined domain. The Importance of the Monte Carlo Methodīefore discussing the Latin Hypercube sampling model, it’s important to begin at a slightly lower level of abstraction: the Monte Carlo method. One of these is Latin Hypercube sampling, which is a method of solving non-deterministic Monte Carlo models, which sees some interesting practical uses in the realm of circuit design and simulation. Specific theorems lend themselves to solving some of the unique and more general problems encountered in PCB design software. Circuit simulation and 3D modeling may be what come to mind first, but there are more powerful implementations available that users may not necessarily be aware of–not to mention the mathematics that support the overarching models. Lurking just below the glossy user interface of modern PCB design applications lay a bevy of powerful mathematical theorems and models that act as the core functionality behind these tools. Some of the Monte Carlo applications a PCB designer may find significant.Ī 6圆 Rubik’s Cube would have a Latin Hypercube arrangement How Latin Hypercube sampling supports non-deterministic Monte Carlo problems.
