The number of evaluation points to include in each batch, typically specified for purposes of concurrent execution of these points.
In the context of adaptive surrogate refinement, batch size requests the generation of multiple refinement candidates that can be evaluated concurrently. This may represent a trade-off between algorithmic efficiency (selecting only the best refinement candidate, one at a time) and scalability (selecting multiple refinement candidates, of decreasing value, to maintain a desired concurrency/load balance).
