The computation of global optima in dual response systems

This paper presents an ANSI FORTRAN implementation of a new algorithm for the global optimization of dual response systems within a spherical region of interest. The algorithm, DRSALG, is a new computational method that guarantees, under conditions that often hold in practice, a global optimal solution for dual response systems. The computer program is illustrated by means of examples found in the recent literature. It is shown that DRSALG can provide better solutions than those previously reported, demonstrating that other methods (e.g., general non-linear programming algorithms) may settle on local optima. Applications of DRSALG to other related problems such as the case of multiple linear secondary responses are discussed.
