# Question

Use the interior-point algorithm in your IOR Tutorial to solve the model in Prob. 4.1-4. Choose α = 0.5 from the Option menu, use (x1, x2) = (0.1, 0.4) as the initial trial solution, and run 15 iterations. Draw a graph of the feasible region, and then plot the trajectory of the trial solutions through this feasible region.
