checker
- Convergence checker.public PAIR optimize(OptimizationData... optData)
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
BaseOptimizer.parseOptimizationData(OptimizationData[])
if they need to register
their own options; but then, they must also call
super.parseOptimizationData(optData)
within that method.
optimize

optData
- Optimization data. In addition to those documented in
BaseOptimizer
,
this method will register the following data:

- Optimization data. The following data will be looked for:
