In statistics and computer software , a convolution randomnumber generator is a type of randomnumber generator that can be used to generate random variate s from certain classes of probability distribution . The particular advantage of this type of approach is that it allows advantage to be taken of existing software for generating random variates from other, usually non uniform, distributions. However, faster algorithms may be obtainable for the same distributions by other more complicated approaches. A number of distributions can be expressed in terms of the possibly weighted sum of two or more random variable s from other distributions. The distribution of the sum is the convolution of the distributions of the individual random variables . Example Consider the problem of generating a randomnumber correspobding to a random variable with an Erlang distribution , math X sim operatorname Erlang k, theta math . Such a random variable can be defined as the sum of k random variables each with an exponential distribution math operatorname Exp k theta , math . This problem is equivalent to generating a randomnumber for a special case of the Gamma distribution , in which the shape parameter takes an integer value. Notice that math operatorname E X frac 1 k theta frac 1 k theta cdots frac 1 k theta frac 1 theta . math One can now generate math operatorname Erlang k, theta math samples using a randomnumber generator for the exponential distribution if math X i sim operatorname Exp k theta math then math X sum i 1 k X i sim operatorname Erlang k, theta . math unreferenced date November 2010 Category Non uniform random numbers ... more details

A random seed or seed state , or just seed is a number or Array data structure vector used to initialize a pseudorandom number generator . The choice of a good random seed is crucial in the field of computer security . When a secret encryption key cryptography key is pseudorandom ly key generation generated , having the seed will allow one to obtain the key. If the same random seed is deliberately shared, it becomes a secret key , so two or more systems using matching pseudorandom number algorithms and matching seeds can generate matching sequences of non repeating numbers which can be used to synchronize remote systems, such as GPS satellites and receivers.

A random permutation is a random ordering of a set of objects, that is, a permutation valued random variable . The use of random permutations is often fundamental to fields that use randomized algorithm s. Such fields include coding theory , cryptography , and simulation . A good example of a random permutation is the shuffling of a card deck deck of cards this is ideally a random permutation of the 52 cards. One method of generating a random permutation of a set of length n uniform distribution discrete uniformly at random i.e. each of the n permutation s is equally likely to appear is to generate a sequence by taking a randomnumber between 1 and n sequentially, ensuring that there is no repetition, and interpreting this sequence x sub 1 sub , ..., x sub n sub as the permutation math begin pmatrix 1 & 2 & 3 & cdots & n x 1 & x 2 & x 3 & cdots & x n end pmatrix . math The above brute force method will require occasional retries whenever the randomnumber picked is a repeat of a number already selected. A simple algorithm to generate a permutation of n items uniformly at random without retries, known as the Knuth shuffle , is to start with the Identity function identity permutation or any other permutation, and then go through the positions 1 through n 1, and for each position i swap the element currently there with an arbitrarily chosen element from positions i through n , inclusive ... of the probability distribution of the number of Fixed point mathematics fixed points of a uniformly distributed random permutation, see rencontres numbers .
