A multivalue method for decision of differential equations including fractional derivatives is offered. A research of approximation and stability of the method is carried out.
Problems of development and realization of an efficient parallelized algorithm to solve elliptic curve discrete logarithm problem (ECDLP) based on Pollard’s rho-method in the computational model SPMD using technology of message passing are considered. It is researched how many central processes are needed and what proportion of distinguished points is needed to be set to optimize an expected working time of this algorithm under the constraints of available memory; analyses the testing results of the developed program.
A problem of low contrast image binarization by the adaptive binariza-tion method and an effective realization of this method based on GPGPU com¬puting paradigm is described.
