AcqOptimizer$new(optimizer, terminator, acq_function = NULL)
Optimize the acquisition function.
fix_distance parameter is set to
TRUE, proposed points are
replaced by randomly sampled ones if their Gower distance with respect
to other proposed points or previously evaluated points falls below the
dist_threshold parameter. Note that these checks are only performed a
single time (and not after a potential replacement of points), i.e., the
data.table::data.table() of optima must not necessarily pass
the checks but most likely will.
data.table::data.table() with 1 row per optimum and x as columns.
