| public PointValuePair optimize(OptimizationData... optData) throws TooManyEvaluationsException Overrides org. Doc from org. Stores data and performs the optimization. The list of parameters is open-ended so that sub-classes can extend it with arguments specific to their concrete implementations. When the method is called multiple times, instance data is overwritten only when actually present in the list of arguments: when not specified, data set in a previous call is retained (and thus is optional in subsequent calls). Important Note Subclasses must override
