Optimizer
Abstract Optimizer class that implements the base functionality each
Optimizer subclass must provide. A Optimizer object describes the
optimization strategy.
A Optimizer object must write its result to the $assign_result() method
of the OptimInstance at the end in order to store the best point and its
estimated performance vector.
$optimize() supports progress bars via the package progressr
combined with a Terminator. Simply wrap the function in
progressr::with_progress() to enable them. We recommend to use package
progress as backend; enable with progressr::handlers("progress").

optimize()
Performs the optimization and writes optimization result into OptimInstance. The optimization result is returned but the complete optimization path is stored in Archive of OptimInstance.
