I am considering applying your tool to solve more complicated problems(more complicated inputs and models), but I worry about the time and spatial complexity.
So I wonder that, in your experiments, if given one case of input and the linear classifier gets a negative output, how much time and memory does it need to solve the integer programming and give the flipset? Does it take a very long time and very much memory? And how about a large number of cases?

What is the reason behind reproducing the same actionable recourse for the same instance although the RecouseBuilder fit twice seperately?

Did you experiment with non-linear models? If so what are the notes?

If not, why? What would be an approach to get recourse on more complex models (DNN) ?

Is it possible with this implementation to impose a sum constraints on one-hot encoded feature columns, so that only one of the colums can be set to 1?

e.g. if you have features x1 x2 x3 = (0,0,1) then (1,0,1) should not be a returned as a counterfactual.

I didn't find it in the code, but it's mentioned in the paper: "Customizing the Action Space.Users can easily customize the set of feasible actions by addinglogical constraints to the IP. These constraints can be used when, for example, a classifier uses dummyvariables to encode a categorical attribute (i.e., a one-hot encoding)."
Did I overlook it?

Thanks!

pip install actionable-recourseleads to the following output for me:

[...]
Requirement already satisfied: pyomo>=5.6.1 in /usr/lib/python3.8/site-packages (from actionable-recourse) (5.6.9)
ERROR: Could not find a version that satisfies the requirement cplex>=12.8 (from actionable-recourse) (from versions: none) 
ERROR: No matching distribution found for cplex>=12.8 (from actionable-recourse)

As CBC and pyomo are up-to-date and pyomo is detected, I wonder why CPLEX errors still prevent the installation.
Note: As this appeared only after I updated my kernel, the error is possibly connected to an issue about my setup that I do not understand.

After setting up the library I executed the notebook in the usage section and it gives,
AttributeError: 'ActionSet' object has no attribute 'align'
how to fix this issue?
