## Name

STEPCV — Define a lower bound for the step size (% of initial step).

## Description

A minimum step size for simulated annealing is specified as a percent (given by
STEPCV=`n.n`

) of the maximum step size (given by
STEP). The step factor “n.n” (which is
(1/NMAX)^{1/2}
by default) yields a minimum step size of n.n × STEP. The current step size is updated internally and usually decreases with the
temperature. The simulated annealing procedure halts when either the current step size drops
below this minimum step size or the random walk is trapped in some minimum on the previous 2
values of the temperature.

### Default value:

(1/NMAX)^{1/2}
