Peter,
This problem is a little more complicated than I first thought. TS does
do an additional test over and above what you request thru the
optimization feature (at least that's the case when optimizing a single
input). However, instead of simply repeating the last test in the
optimization series, it appears TS repeats the optimization for the
"best" (whatever you've defined as "best") run.
You'll have to add code to your system so that it remembers the parameter
value for the "best" run then some more code to test for that value when
doing your print statement.
