c++ Programming Glossary: probabilityWhy do people say there is modulo bias when using a random number generator? http://stackoverflow.com/questions/10984974/why-do-people-say-there-is-modulo-bias-when-using-a-random-number-generator 3 does not produce the numbers between 0 and 2 with equal probability When rand returns 0 3 6 or 9 rand 3 0 . When rand returns 1.. we analyze this statistically we very quickly see that the probability of getting a 0 is 4 11 1 is 4 11 but 2 is 3 11. This does not.. does not generate the numbers between 0 and 2 with equal probability. Of course for small ranges this might not be the biggest issue..
What is the optimal algorithm for generating an unbiased random integer within a range? http://stackoverflow.com/questions/11758809/what-is-the-optimal-algorithm-for-generating-an-unbiased-random-integer-within-a buckets and 100 balls the maximum deviation from the ideal probability among buckets is less for the floating point extrapolation than..
What is a simple example of floating point/rounding error? http://stackoverflow.com/questions/249467/what-is-a-simple-example-of-floating-point-rounding-error in C Edit For example say I have an event that has probability p of succeeding. I do this event 10 times p does not change.. not change and all trials are independent . What is the probability of exactly 2 successful trials I have this coded as double p_2x_success..
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 percentage of the time 20 or 50 or whatever that is the probability that you will catch it in the act on each sample. So that is.. assume it is either 0.1 0.2 0.3 ... 0.9 1.0 and the prior probability of each of these possibilities is 0.1 so all of these costs.. P o 2 2 0.385 The last column says that for example the probability that f 0.5 is 92 up from the prior assumption of 60 . Suppose..
Random number generation in C++11 , how to generate , how do they work? [closed] http://stackoverflow.com/questions/7114043/random-number-generation-in-c11-how-to-generate-how-do-they-work that generate the numbers 0 1 ... 10 each with equal probability think of this as the classic rand . Now you want a random number.. want a random number in the range 0 1 2 each with equal probability. Your knee jerk reaction would be to take rand 3 . But wait..
Need for predictable random generator http://stackoverflow.com/questions/910215/need-for-predictable-random-generator of minimum rolls it returns a fair hit based on the normal probability. If the observed probability from past rolls makes it seem unfair.. fair hit based on the normal probability. If the observed probability from past rolls makes it seem unfair it returns a fair ifying.. unfair based on boundary probabilities. For instance for a probability of 20 you could set 10 as a lower bound and 40 as an upper bound...
