Evaluation Queue

The EvaluatorControl manages the evaluations. It has a queue of EvalQueuePoints which are points that need to be evaluated. The points are generated by SearchMethods, PollMethods, or other Steps derived from IterationUtils. The EvaluatorControl also handles the Evaluator(s).

The queue is implemented by a vector.

Points may be ordered before evaluation. This is useful for opportunistic evaluation, more so when there is little CPU available (few threads for OpenMP).

There are multiple sorting criteria: DIR_LAST_SUCCESS, LEXICOGRAPHICAL, RANDOM, SURROGATE; others like QUAD_MODEL should be added. See parameter EVAL_QUEUE_SORT. The default is DIR_LAST_SUCCESS.
