Absolute convergence tolerance
Alias: none
Argument(s): REAL
Default: -1. (use NL2SOL internal default)
absolute_conv_tol
(NL2SOL's afctol
) is the absolute function convergence tolerance (stop when half the sum of squares is less than absolute_conv_tol
, which is mainly of interest on zero-residual test problems).
The internal default is a function of machine epsilon (as limited by function_precision
). The default is selected with a value of -1.
