Lunberger, Yinyu Ye, "Linear and Nonlinear Programming", Third Edition, Springer (Chapter 8.1 Golden Section, Chapter 8.6 Steepest Descent) The pseudocode of Steepest Descent algorithm is given as follows: Algorithm 2 Steepest Descent 1: procedure STEEPEST DESCENT 2: Step 1: Initialization: 3: 4: & 6: 7: Initialize Xo = 0 and N = 150(marimum iteration number) Determine the values of the stopping criterias 1-10-10, 2-10-10, 3= 10-10 Set k = 1 Step 2: Calculate the gradient vector f(x) at x Calculate the direction vector p = f(x) Minimize f(x + p) with respect to n via golden section. Hint: You can set n = 1. 10: Update X+1=Xk+ 1/Pk 11: Step 3: Termination 12: Calculate Aff(x+1)-f(x) and Ax=Xk+1-Xk 13: if Af & then, terminate algorithm since the value of the objective function does not change if ||Ax| 2 then, terminate algorithm since the value of the variable does not change if Vf(x)| 3 then, terminate algorithm since the value of the variable does not change k+k+1.. 8: 9. 14: 15: 16: 17: if k= N then, terminate algorithm owing to reaching marimum iteration number. 18: Step 4: Obtain solution: Implement the above code using Matlab m-file enviroment.
