查询词典 probability distribution function

It is proved that if the optimal solution tree has an inter-node, the necessary and sufficient condition that tree structure GAs are solution foundable is that the initial population contains an inter-node; the upper limit of solution foundable probability is also calculated and the population size is proved to increase at most in a polynomial of increasing problem complexity and the probability upper limit.

Secondly, the properties of output sequences of stop-and-go clocked combiners are discussed. It is proved that the output sequences are stationary and obey strong law of large numbers and central limit theorem. Using the probabilistic model properly built, we analyze the rate of coincidence between the output sequences of two kinds of generators with basic operations and corresponding LFSRs sequences. All the computational formulae are derived. A recursive algorithm for efficiently computing the poster probability of partial input strings and corresponding joint probability is introduced. Moreover, divide-and-conquer attacks on this kind of generators which reconstruct the initial states of the input stop-and-go generators individually are proposed.
