N2 - A new correlative randomized algorithm is constructed by applying simple randomization of the majorant cross section (alignment, delta tracking) algorithm and using a one-dimensional distribution and the correlation length of the stochastic medium. The value of this parameter can be adjusted using simple test analysis. The performed computations have confirmed the practical efficiency of the new algorithm.
