The article explores the ideas of using parsing strategies to optimize the performance of parser combinators. Considered as an example of the service data parsing PetitParser, as well as the work of the parser compiler. The optimization and analysis of the performance of the parser is also described in detail. In various examples, their effectiveness was evaluated and a comparative analysis was conducted.

The article describes development of the algorithm and realizing software application for mathematical model of stationary liquid stream influence to the spherical body under viscous film. The algorithm is designed to obtain the formula for calculating of stationary liquid stream influence to the spherical particle. Realizing software application is created. In Russia all rights for the software application are protected by the state certificate of computer program registration.
