Hi I got an objective function for which i have to find the optimum value but the solvers asks starting point which I do not know. The bounds are [2,200,43,500] & [2,1200,78,1800] I cannot give so much of combinations of starting value Plz help me in this...my objective function is: f=(1/1+exp(15.02+(6.09*(1(100(95*exp((0.03353*a(1)*a(1)*a(1)*a(1))(0.2179*a(1)*a(1)))/100))))+(4.88*(1(0.5*(1/1+exp(3.1180.00215*a(2))))+(0.5*(1/(1+exp(3.230.00117*a(2)))))))+(4.73*(11/(1+exp(9.540.134*a(3)))))+(3.7*(11/(1+exp(1.017+0.00558*a(4)))))));
