On Thursday, I presented a short example to demonstrate the effects of alphabet extension on the composition of two FSP processes. A student asked me to post that FSP. Here it is:
range T = 0..50 set VarCoins = {in.coin[T], out.coin[T]} COINTRACKER = (in.coin[5] -> out.coin[10] -> COINTRACKER). TROUBLEMAKER = (in.coin[5] -> CHOICE), CHOICE = (out.coin[10] -> TROUBLEMAKER | out.coin[15] -> TROUBLEMAKER). ||TRACKME = (COINTRACKER || TROUBLEMAKER). COINTRACKER2 = (in.coin[5] -> out.coin[10] -> COINTRACKER2) + VarCoins. ||TRACKME2 = (COINTRACKER2 || TROUBLEMAKER).
