Evaluator
An evaluator should communicate with the simulation oracle to determine solutions for requests for evaluation from solvers.
Parameters
the problem that the evaluation of responses will be used on
the provider of responses from the simulation oracle
a cache that can be used instead of a costly simulation evaluation
the maximum number of direct replications permitted by the evaluator. The default is Int.MAX_VALUE. This can be used to control the total number of replications executed by the simulation oracle.
Constructors
Properties
Indicates if the number of replications budgeted has been exceeded or not.
The maximum budget (in terms of number of replications) within the evaluations performed by the simulation oracle.
The total number of remaining replications that can be performed by the simulation oracle.
The total number of evaluations performed via the cache.
The total number of replications satisfied by the cache.
The total number of evaluation requests received that were duplicates in terms of inputs.
The total number of evaluations performed. An evaluation may have many replications.
The total number of evaluations performed via the simulation oracle.
The total number of replications performed by the simulation oracle.
The total number of replications requested across all evaluation requests.
The total number of evaluation requests that were received.
Functions
Processes the supplied requests for solutions. The solutions may come from an associated solution cache (if present) or via evaluations by the simulation oracle. The list of requests may have duplicated inputs, in which case, the solution will also be a duplicate. That is, no extra evaluations occur for duplicates in the list of requests. Any new solutions that result due to the processing will be entered into the cache (according to the rules governing the cache).
Processes the supplied request for a solution. The solution may come from an associated solution cache (if present) or via an evaluation by the simulation oracle. A solution that results due to the processing will be entered into the cache (according to the rules governing the cache). If the request is input range-infeasible, then a bad and infeasible solution will be returned.
The evaluator collects some basic counts (statistics) on its evaluations. This function resets all counters to 0, perhaps in preparation for another evaluation run.
