Actually, I wondered that it run. 2- I prefer to describe my problem briefly: - my problem is to optimize the layout of a number of wind turbines (say 16) in series in order to maximize the power produced. - I have the technical data for 28 types of wind turbines, a vector of 10 elements, must be used in calculation if any type of turbine is chosen at any location. - besides, each turbine may operate at a rage of hub heights. - the proposed location of each turbine also an aspect of optimization. - so, for the 16 proposed turbines in series, I have 3 variables (turbine type, hub height, and X-coordinate), but the first variable is linked with the 28 x 10 technical data matrix (this is the source of extensively calling the data from the matrix). - the wake effect of each turbine on all downstream turbines is calculated based on their type, height, and location. - I have a specified LB and UB vectors, and have one linear equality constrain [sum (distance among turbines) = a specified total length] I hope these released secrets regarding to my problem may help you to help me :) thank you again, Mamdouh.
