This chapter starts with a general survey of the field of optimization and describes some motivating examples from chemometric data analysis. Then we delve into methods for solving unconstrained and constrained optimization problems, along with two popular strategies for global convergence. Finally, we ...

We consider Rosenbrock’s function from Examples 4.3 and 5.5. We have tried different updating formulas and line search methods. The line search parameters were chosen as in Example 4.3. With the starting point x0 = [ ?1.2, 1 ] , the following numbers of iteration steps and evaluations of...
Many of the optimization functions determine the direction of search by updating the Hessian matrix at each iteration, using the BFGS method (Equation 9). The functionfminuncalso provides an option to use the DFP method given inQuasi-Newton Methods(setHessUpdateto'dfp'inoptionsto select the DFP...
I have a Large scale MILP problem which I am trying to solve through meta-heuristic methods. It only contains linear constraints. While solving through Genetic Algorithm, the matlab does provide option to consider constraints. But there is no option regarding co...
The effectiveness of the proposed method has been shown by some numerical examples. We find that the proposed method due to the q-gradient converges fast for a set of test problems with different starting points. The inclusion of q-calculus in other conjugate gradient methods deserves further ...
