Dear colleagues, I would appreciate if anybody could recommend me a freeware simulated annealing (or something similar) package which would have the following features.
1) would allow to construct the starting model for every event as combination of N1 atoms at explicitly specified positions + N2 atoms randomly generated 2) would allow to choose between fixing or refining the atomic positions for the N1 group during MC cycles 3) would allow minimal and maximal distance constraints with controlled "flexibility" I admit that all (or, at least, many) such packages do have those features (they are quite obvious), but I would prefer not to try all possibilities. 4) (optional) would allow experimental pattern (rather than F's) as input (with given profile parameters and, for example, point-by-point background); support neutron TOF data... Sincerely, Maxim. _______________________________________ Maxim V.
