Why is SQP better than Augmented Lagrangian for nonlinear programming?
In the technical report on Galahad[1], the authors state, in the context of general nonlinear programming problems,
To our minds, there had never really been much doubt that SQP [sequential quadratic programming] methods would be more successful…

Gradient of function after renormalization of variables
I have to minimize a function $f(\mathbf{x})$, where the vector $\mathbf{x}\in\mathbb{R}^n$ satisfies $|\mathbf{x}|=1$. So I tweaked the code of $f$ so that it renormalizes $\mathbf{x}$ as the first step, and this allows me to avoid adding the…

minimization of normalized constrained quadratic function
I'm a computer science student. Please I need a help in solving a constrained normalized quadratic function. I'm familiar with solving quadratic constrained optimization function with matlab by providing a symmetric matrix and a vector as inputs for…

2D Multilateration with constraints as distance information
In my current problem, I am looking for an algorithm to reconstruct the position of multiple points in the 2D euclidean plane with incomplete distance information, $d_{ij}=||x_j-x_i||\in\text{dom}_a$.
E.g. Information is:
$x_i$: $\{d_{ii},d_{ij},…

Software Implementing Jiles-Atherton
I have been doing much research on the internet to see if there was a FEM simulator that natively implemented the Jiles-Artherton model whether it be commercial or open source
So far, my conclusion is that there is none. Before I make a final…

Optimization for differential and nonlinear system
I want to minimize a cost function for a differential-nonlinear system (dynamic).
Is it possible to use this software? How can I do it?
Best regards,
