Container for results of hyperparameter tuning. Contains the obtained point in search space, its performance values and the optimization path which lead there.
Learner that was optimized.
Control object from tuning.
Named list of hyperparameter values identified as optimal.
Note that when you have trafos on some of your params,
x will always be
on the TRANSFORMED scale so you directly use it.

Note that when you have trafos on some of your params, the opt.path always contains the
UNTRANSFORMED values on the original scale. You can simply call

OptPath will have a
extra column which contains error dump traces from failed optimization evaluations.
