WebProhibited Areas Prohibited areas contain airspace of defined dimensions identified by an area on the surface of the earth within which the flight of aircraft is prohibited. Such areas are established for security or other reasons associated with the national welfare. Webproblem with valve-point effects. However, prohibited operating zones have not considered. The aim of this paper is propose a hybrid -DESQP for solving the DEED with valve-point effects and prohibited operating zones. The DE is used to find a near global solution and SQP is used as a local search to determine the optimal solution at the final.
