The efficiency of convergence is crucial in real-world applications where time and computational resources are limited, making it imperative to develop SQP algorithms that can swiftly converge to the desired solution.

*Handling of non-linear constraints*

Another important aspect to consider in SQP algorithms is the handling of non-linear constraints. Non-linear constraints pose a significant challenge in optimization problems, as they cannot be easily incorporated into the mathematical model. SQP algorithms address this issue by formulating the constraints in an iterative manner, updating the active set of constraints at each iteration. This allows for the most efficient use of computational resources, as only the active constraints need to be considered at each iteration. Additionally, SQP algorithms employ penalty function methods to handle non-linear constraints, where a penalty term is added to the objective function to penalize violations of the constraints. This penalty term helps steer the optimization process towards satisfying the constraints while still optimizing the objective function.
