Using galeShapley.collegeAdmissions with incomplete preferences of students and colleges

Hello, Is this possible to use galeShapley.collegeAdmissions with incomplete preferences of students over colleges and of colleges over students?

No, I don't think there's an easy way to do that.

You might be able to improvise a bit though. For the case when students have incomplete preferences over colleges, you could add a "placeholder college" with lots of spots and add that placeholder college to students' preference orderings just above those colleges for which their preference orderings are incomplete. Students who end up at the placeholder college would be considered unmatched.

Thanks a lot for the answer and the tip, it is very helpful. For the colleges incomplete preferences, I will just try adapt the slot vector so that the capacity constraints takes into account the fact that some applicants are not ranked by colleges. I'll try this way, thanks again.
