Selection with pre-selected set

[M-A-Hassan]

Hi,

Is there a way to pass a preselected set of data to the optimizer to be considered while calculating the gain?
The preselected set is user-defined input to the optimizer and will not be altered or modified in any way by the optimizer.

Thanks for the effort and making this package available.

Yes. Look at this argument in the functions: https://github.com/jmschrei/apricot/blob/master/apricot/functions/featureBased.py#L161

Sorry for taking so long to reply.
Now I have tried it, but it seems that this way only works if your initial set is a subset of the data.
Please take a look at this:

apricot/apricot/functions/graphCut.py

Line 243 in bf86e69

elif self.initial_subset.ndim == 2:

When a try to pass a 2 dim array, as my initial set, this line of code raises the following value error:
ValueError: When using facility location, the initial subset must be a one dimensional array of indices.
