The last column does not mean number of nodes. It mean that value of an integer variable that is called nodes. This variable can get values between -2,147,483,648 and 2,147,483,647 and is updated by the C commands nodes++; nodes++ does not mean always increasing the value of nodes by 1 and when nodes=2,147,483,647 and you do nodes++ you get -2,147,483,648 Uri
