High Quality Content by WIKIPEDIA articles! Until the mid-1970s, agriculture in Syria had been the primary economic activity. At independence in 1946, agriculture (including minor forestry and fishing) was the most important sector of the economy, and in the 1940s and early 1950s, agriculture was the fastest growing sector.

However, by the late 1950s, little land that could easily be brought under cultivation remained. During the 1960s, agricultural output stagnated because of political instability and land reform. Between 1953 and 1976, agriculture`s contribution to GDP increased (in constant prices) by only 3.2 percent, approximately the rate of population growth. From 1976 to 1984 growth declined to 2 percent a year. Thus, agriculture`s importance in the economy declined as other sectors grew more rapidly.
Эволюционные алгоритмы обусловлены процессами оптимизации, которые мы наблюдаем в природе, такими как естественный отбор, миграция видов, стаи птиц, человеческая культура и муравьиные семьи. В данной книге рассматриваются история, теоретические основы, математический аппарат и программирование алгоритмов эволюционной оптимизации. Рассмотренные алгоритмы включают в себя генетические алгоритмы,...
