THE RAMESES ALGORITHM FOR MULTIPLE EQUILIBRIA .2. SOME FURTHER DEVELOPMENTS

The algorithm RAMESES has been made more efficient by incorporation of additional procedures: to extrapolate to the next point by an exact polynomial of any desired order, to control the gain on the adjustment of each independent species, and to optimize the initial guess. The need to consider electroneutrality is emphasized, and some problems with convergence criteria and synthetic test systems are discussed. Some conditions for objective algorithm testing are proposed. © 1990.
