Method of Minimizing the Global Free Energy with SUMT Program

By improving on the FORTRON program of SUMT, the algorithm of minimizing the global free energy of the system (G), which is the nonlinear programming with equality constraints, have solved. The precision of the algorithm is higher than the others. The program suit to PC computers. The main parts improved on the program is that equality constraints must be forced to a specified precision, before the main program converges.
