hi, all: I noticed that the old random number generator interface in "random.h" is used defaulty by some algorithms such as RED.
In random.h, the random number is got from the stream of default RNG object. Thus, if multiple RED queue are defined, the random numbers they used to make the decition is actually a sub-stream (note this is not the substream of the RNG class) of a stream. In such a case, the decition may not be so independent. This problem also arise when we use the class RandomVariable while do not re-seed them. I am not fimilar with the algorithm of RNG. My question is that how far this may mislead to our analysis? Regards ciel 2006/01/06
