make_tunable {adoptr} | R Documentation |
The methods make_fixed
and make_tunable
can be used to modify
the 'tunability' status of parameters in a TwoStageDesign
object.
Tunable parameters are optimized over, non-tunable ('fixed') parameters are
considered given and not altered during optimization.

for
converting tunable parameters of a design object to a numeric vector (and back),
and minimize
for the actual minimzation procedure
