Global simulation approach

New Horizons for Computational Chemistry Global Simulation Approach... 

Our global subdivision approach is not sensitive to such a situation. Over sufficiently long run times of direct simulation both methods eventually yield roughly the same results, see Fig. 6. 

A successfid indexing of the powder diffraction pattern, which can often be done automatically, yields the unit cell dimensions and information on possible space groups. The chemical analysis and sorption data indicate the framework density, or number of tetrahedra per unit cell. The challenge is then to position these tetrahedra within the unit cell such that (1) they fully interconnect in a sensible manner and (2) the necessary analytical data are reproduced. These structural constraints are quantified in an energy expression and simulated annealing [33,34] is employed as the global optimization approach. 

In practice, a blend of local and global SA approaches may be employed. Quantitative uncertainty in the form of standard errors may be available only for some model inputs. Multiple executions of the simulation to characterize the global SA of the quantified parameters may be undertaken conditional on a series of fixed-...

TlyperChern has a facility for a more systematic approach to the global min im urn than just choosing ran dom startin g poin ts. This facility is associated with the idea of simulated annealing. 

An approach to overcome the multi minima problem of proteins is simulated annealing (SA) run. Besides global molecular properties such as structural and thermal motions, functional properties of fast biological reactions can also be studied by MD.
