Accelerated sampling of energy landscapes
… using graphics processing units (GPUs). Basin-hopping global optimisation was treated using a version of the limited-memory BFGS algorithm adapted for CUDA, in combination with GPU-acceleration of the potential calculation. The Lennard-Jones potential was implemented using CUDA, and an …

Energy Landscapes of Hybrid Potentials Based on NMR Data
… incorporation of NMR structural constraints into basin-hopping via NMR hybrid potentials produced improved structure prediction results, in terms of accu- racy and efficiency, for benchmarking systems trpzip 1 and DP5. Energy landscapes for NMR hybrid potentials were analysed, which justified the …

Automated global optimization of low-energy trajectories using a hybrid optimal control framework
… number of phases. The inner loop uses Monotonic Basin Hopping to seed initial guesses for the non-linear problem solver. Solutions are presented in the form of Pareto fronts trading multiple-objectives. The work described here presents the motivation for such a tool, the mathematical models that …

Automated trajectory planning for multiple-flyby interplanetary missions
… a nonlinear programming solver and the monotonic basin hopping (MBH) global search heuristic. The methods developed here are demonstrated to optimize a set of example trajectories, including a recreation of the Cassini mission, a Galileo-like mission, and conceptual continuous-thrust missions to …

On Critical Care Data and Machine Learning Loss Function Landscapes
… neural network loss functions are found using basin-hopping methods implemented with the open source software GMIN. In this way, the landscape of the loss function defined by the neural network model can be explored. Area Under the Curve (AUC) values were used to evaluate these models. Two …

Energy Landscaping - On the Relationship between Functionality and Sequence Mutations for Multifunctional Biomolecules
The process of protein and RNA folding has been understood in general terms through the principle of minimal frustration, and is usually thought of as being guided by a folding funnel on the energy landscape, which is based around the native structure. However, more recently, various biomolecules …

Automated planetary satellite tour planning with a novel low-thrust direct transcription method
Upon completion of the heliocentric leg of its mission, it is almost always the case that an interplanetary spacecraft has scientific objectives to accomplish. This is especially true if the spacecraft performs a planetary moon tour. Over the past decade, mission designers have started to consider …

Robust preliminary design for multiple gravity assist spacecraft trajectories
The development of a new spacecraft trajectory design method most often occurs because a particular capability does not exist. The invention is usually considered successful so long as it is capable of producing solutions to the problem in question, and thus satisfies a particular design …
