What can I use to profile C++ code in Linux? http://stackoverflow.com/questions/375913/what-can-i-use-to-profile-c-code-in-linux is on the call stack some fraction f of the time and thus costs that much . For simplicity suppose we don't know what f is.. of each of these possibilities is 0.1 so all of these costs are equally likely a priori. Then suppose we take just 2 stack.. So Bayes allows us to update our estimate of the probable cost of I . If the amount of data is small it doesn't tell us accurately..
