OLDNLLSQ — Superseded by TRUSTG.
NLLSQ performed a geometry optimization to minimize the gradient is performed using Bartel’s method (a Non-Linear Least Squares gradient minimization routine). In AMPAC 7, NLLSQ was depreciated but could still be accessed using OLDNLLSQ. Now in AMPAC 8, OLDNLLSQ is no longer supported and will cause the job to exit. Either TRUSTG, LTRD, or TS should be used in place of NLLSQ or OLDNLLSQ.
