A projected-search interior-point method for nonlinearly constrained optimization Open
This paper concerns the formulation and analysis of a new interior-point method for constrained optimization that combines a shifted primal-dual interior-point method with a projected-search method for bound-constrained optimization. The m…

An $LDL^T$ Trust-Region Quasi-Newton Method Open
For quasi-Newton methods in unconstrained minimization, it is valuable to develop methods that are robust, i.e., methods that converge on a large number of problems. Trust-region algorithms are often regarded to be more robust than line-se…

Projected-Search Methods for Bound-Constrained Optimization Open
Projected-search methods for bound-constrained optimization are based on performing a search along a piecewise-linear continuous path obtained by projecting a search direction onto the feasible region. A benefit of these methods is that ma…

Verification of WAFC in-flight icing forecasts using satellite observations Open
<p>In-flight icing constitutes a major hazard to aviation, and so it is vital to be able to forecast the risk of icing accurately. The Met Office is one of two World Area Forecast Centres (WAFC) to routinely produce and validate icin…

Assessing model performance by weather regime transitions  Open
<p>Having the ability to stratify a model&#8217;s performance by weather type is not only beneficial to a weather forecaster when making decisions, but it is also important for end users, whether they be scientists looking to imp…

Probabilistic Performance-Based Optimum Seismic Design Framework: Illustration and Validation Open
In the field of earthquake engineering, the advent of the performance-based design philosophy, together with the highly uncertain nature of earthquake ground excitations to structures, has brought probabilistic performance-ba... | Find, re…

A study of structure-exploiting SQP algorithms for an optimal control problem with coupled hyperbolic and ordinary differential equation constraints Open
In this article, structure-exploiting optimisation algorithms of the sequential quadratic programming (SQP) type are considered for optimal control problems with control and state constraints. Our approach is demonstrated for a 1D mathemat…
