Model:	coupon v.1 (DTMC)
Parameter(s)	N = 15, DRAWS = 4, B = 5
Property:	exp_draws (exp-reward)

Settings specific for this benchmark: '--unsafe' = compile model without bounds and assignment checks, '--max-run-length 0' = do not impose a limit on the maximum length of a simulation run (which is anyway more of a model debugging feature), '--timeout 1680' = stop after 28 minutes of simulation and return the estimate at that point even if the desired confidence is not yet met.
