The Fabric port was developed by TechnoVision. It was originally developed by al132, but is now developed and maintained by Dark_Arcana and Timbroglio.

So long as there is a chance for an observation to be made, no matter how small, it is considered part of the phase space.Alchemistry is an extensive chemistry mod and a spiritual successor of Minechem. It should also be noted that "near zero probability" and "always zero probability" are two distinct things when considering phase space.There are a number of strategies to address lack of overlap between target spaces, but determining the best way for any given situation is still a research question.

Efficient free energy calculations require significant phase space overlap.

The degree to which the phase spaces are shared is called the "phase space overlap".

If one wishes to do this, substitute all potential energies, \displaystyle will, the two phase spaces are not the same and these methods will either break down or return very error-prone results.

constant temperature is maintained: (discussed below).

Non-bonded terms made up of point charges and Lennard-Jones repulsion/dispersion terms.A standard molecular mechanics model will be assumed this includes:.Free energy calculations can usually be set up without these assumptions, but we'll make these assumptions to simplify the explanations. The assumptions listed here are carried out through the rest of the fundamentals sections. There are of course many factors and checks that must be done to ensure accuracy and robustness of the calculations, many of which will be shown in the rest of the free energy fundamentals pages. This is roughly the same definition of alchemy from old in that we are changing the properties of the atoms to be something else, although we do it in a mathematically sound and rigorous manner hence, the term "alchemical" was coined as many free energy calculations are "like alchemy" in their pathways and methods. With these observations in mind, it was found that we can simulate modifications to atoms which can change their properties to reflect non-physical or entirely different species. Furthermore, since we are doing simulations, we are not limited by experimentally observable conditions so long as we are meticulous with our calculations. Because free energy is a state variable (path independent), we can design simulations that provide a convenient pathway to computing free energy. How computational free energy adopted the name takes a bit of understanding of simulation limitations and the properties of what we are calculating.Ĭonsidering that the natural evolution of some of the processes we try to model are well beyond reasonable simulation time scales, we must come up with very efficient ways to compute the free energy differences. When people first hear the word "alchemy," they usually think of the medieval alchemists who were trying to turn lead into gold, or other such transformations.

One of the first questions, and often most confusing points, about a number of free energy calculations is why we refer to them as "alchemical" changes in a large number of computational methods. 3.1 Facts from the Free Energy Difference Definition.
