mlr_optimizers_async_design_points {bbotk}

Asynchronous Optimization via Design Points

Description

OptimizerAsyncDesignPoints class that implements optimization w.r.t. fixed design points. We simply search over a set of points fully specified by the ser.

Dictionary

This Optimizer can be instantiated via the dictionary mlr_optimizers or with the associated sugar function opt():

mlr_optimizers$get("async_design_points")
opt("async_design_points")

Parameters

design

data.table::data.table
Design points to try in search, one per row.
