Easy and flexible mixture distributions

Reversed hazard rate of the mixture distributions

In this article study summery of reversed hazard rate and mixture distributons then introduce reversed hazard rate mixture and waiting times of failure also introduce mixture reversed hazard rate additive modele and multiplicative and introduce behavioure mixture of k increasing reversed hazard rate (IRFR) Increasing(IRFR).

Are all distributions easy?

Complexity theory typically studies the complexity of computing a function h(x) : {0, 1}n → {0, 1}m of a given input x. We advocate the study of the complexity of generating the distribution h(x) for uniform x, given random bits. Our main results are: • There are explicit AC circuits of size poly(n) and depth O(1) whose output distribution has statistical distance 1/2n from the distribution (X,...

Hard and Easy Distributions of SAT Problems

We report results from large-scale experiments in satis-ability testing. As has been observed by others, testing the satissability of random formulas often appears surprisingly easy. Here we show that by using the right distribution of instances, and appropriate parameter values, it is possible to generate random formulas that are hard, that is, for which satissability testing is quite diicult....
