Model¶

write lp¶

instance.write('model.lp', io_options={'symbolic_solver_labels': True})

warm start¶

• tee Print the progress of the solver during optimizing.

• logfile: We can also write the log to a file.

• timelimit: The solver will stop after 600 seconds and keep the best solution.

  instance = model.create()
  instance.y[0] = 1
  instance.y[1] = 0

      opt.options['TimeLimit'] = 600
      cpx.options['MIGap'] = 0.000001
      results = cpx.solve(instance, tee=True, warmstart=True)
