CADETProcess.optimization.COBYLA.get_callback

COBYLA.get_callback(optimization_problem: OptimizationProblem) → Callable

Configure callback function.

Parameters:

optimizationOptimizationProblem

Returns:

Callable

The callback funcction

Note, different optimizers in Scipy support different callback signatures.

We try to use the more modern OptimizeResult signature which is more likely

to also contain the current best value. For older optimizers, xk is used.

However, there is ambiguity in what that point actually is (see also:

scipy/scipy#21061).
