摘要：Increasing accuracy of weather forecasts for ocean areas (wave faclors,limits of ice),development of communication means,receiving and computations of naviga– tional and weather information (satellite omnunication,computer programming) as well as development of theoretical basics of optimization and decision making process permit operational compulations of optimal routes for ships on the oceans.Using Bemard Wisniewski d)ynanical programming,route selection is made objectively,taking into account dy– namical changing weather conditions,ship characteristics and assumed optimization criteria.For computations different types of algorithms may be used:from graph theory,evolutionary algorithms based on genetic algorithms as well as isochrone ones.Follow ing an example of results of ships voyages recommended by Polish Steamship Compary routing centre,3% of time voyage saving in comparison with seasonal voyages were obtained.
其他摘要：Pre–conditions and methodological bases of theoretical researches of geometrical constituents of composition of illustrations are certain.On the basis of the set geomet rical principles original illustrations are created to the sur realism novel Brotigana,'In water–melon sugar’,that connected in itself an emotional vividness,logically motivated originality,simplicity,structural clarity of construction, assisting deeper interpretation of text.
