Description
I want to create a bus schedule for a given time table. I have used PULP for the optimization problem (MIP). But I get multiple errors and I need some help with the entire code for scheduling. I also want to make spans and show the results.
Error 1: '<=' not supported between instances of 'list' and 'int'
