$TRURST group (optional, relevant for RUNTYP=TRUDGE)
This group specifies restart parameters for TRUDGE runs and accuracy thresholds.
KSTART indicates the conjugate gradient direction in which the optimization will proceed. ( default = -1 )
FNOISE accuracy of function values.
TOLF accuracy required of the function (Def. 0.001)
TOLR accuracy required of conjugate directions (Def. 0.05)
For geometry optimization, the values which give better results (closer to the ones obtained with gradient methods) are: TOLF=0.0001, TOLR=0.001, FNOISE=0.00001
