This looks like a bug in Sage or Sage's GLPK interface.
The practical solution that worked for me was to run the calculation in a separate process using Sage's parallelization features. It can be done by wrapping the feedback arc set calculation with a few function that has the @fork or @parallel decorators.

This looks like a bug in Sage or Sage's GLPK interface.
The practical solution that worked for me was to run the calculation in a separate process using Sage's parallelization features. It can be done by wrapping the feedback arc set calculation with a few function that has the @fork or @parallel decorators.
I can confirm that even after a several-day running time, the calculation has not stalled.
