what do you mean by "optimise the eigenvector"?

Improving the Eigenvector to get better answer

And now we should ask what do you mean on "to get the better answer"? In AHP the eigenvector's elements are dependend on the Saati's matrix content, so if you are not satisfied with your eigenvector, you should change the expert's estimations on pair comparisons. But how to influence on experts nobody knows )

Sure, we cannot influence on experts to get the best answer, but we can do that by another mathematical application

To optimize the eigenvector in ANP (Analytic Network Process), ensure consistent pairwise comparisons, address dependencies accurately between elements, and verify the consistency of the decision-making process to enhance the reliability of the eigenvector results.
