Faster Evolutionary Multi-Objective Optimization via GALE, the Geometric Active Learner
… iteratively improved approximations to the Pareto frontier, i.e. the set of best solutions contained along a trade-off curve of competing objectives.;To approximate the Pareto frontier, one method that is ubiquitous throughout the field of optimization is stochastic search. Stochastic search …

A Metamodel based Multiple Criteria Optimization via Simulation Method for Polymer Processing
… The method is able to approximate a set of Pareto solutions without having to evaluate a large number of simulations. In order to accomplish this, design of experiments, metamodeling, Data Envelopment Analysis, and Pareto optimality are combined. After first testing the method with …

Embedded Software-Defined Radio Architectures for 6G Cellular Networks
… enabling the identification of the Pareto frontier. Analysis of SDR system architectures on the Pareto frontier reveals that the performance of direct RF sampling SDR architectures is highly competitive with industry-standard IF sampling. The tradespace is also used to analyze the …

Modeling Aspects of Military Readiness
… these decisions and can be used to generate a Pareto frontier between personnel readiness and applicant satisfaction. Then, we develop a tractable solution approach for finding an approximate Pareto frontier using a local search algorithm. We use data from the U.S. Army's 2020 assignment market …

Visualizing Multidimensional Data with General Line Coordinates and Pareto Optimization
… from one graph to the next. Visualizing the Pareto Frontier with GLC-L allows n-D data to be viewed at once, compared to typical methods that are limited to 2 or 3 objectives at a time. This method details the process of selecting a ”best” case, from a group of equals in the Pareto Subset and …

Learning to Trade Off Performance and Safety in Mixed Autonomy Traffic
… level. This investigation automatically produces Pareto frontier curves for four diverse traffic scenarios based on established mixed traffic benchmarks. The results of this study will inform decision-makers regarding inherent trade-offs in traffic control systems, and this framework can be …

Essays on coordination, cooperation, and learning
… pushes players away from the full-information Pareto frontier. Unlike in one-shot two-by-two games, the global games information structure does not yield equilibrium uniqueness, however, by making it harder to coordinate, it does reduce the range of equilibria and gives bite to the notion of …

System Design and Evaluation of Spectrum Management Architectures for Co-Primary Sharing in the 37 GHz Band
… multi-dimensional tradespaces and identify Pareto-optimal solutions. Results indicate that semi-dynamic spectrum management systems with decentralized or hybrid coordination topologies consistently dominate the Pareto frontier across all demand levels. Compared to fully dynamic systems, …

Essays on development finance
… insurance fall well short of the constrained Pareto frontier under both individual and joint liability, joint liability increases observed insurance transfers. Equity-like financing overcomes both of these inefficiencies and merits further testing in the field. Chapter 2 investigates the …

Technology Roadmapping for Energy Storage using ZEBRA Batteries
… the cost of it for each solution. Cases on the Pareto frontier were selected and analyzed to understand the performance of batteries. Finally, a Life Cycle Analysis of the system, a comparison with Lithium-Ion Batteries, and a sensitivity analysis were performed. The main outcome of this work is …

Improvement and measurement of neural style transfer
… style transfer. }Admissible methods lie on a Pareto frontier (i.e. improving E reduces C, or vice versa). Three methods are admissible: Universal style transfer produces very good C but weak E; modifying the optimization used for Gatys' loss produces a method with strong E and strong C; and a …

Optimal routes for electric vehicles facing uncertainty, congestion, and energy constraints
… In addition, for example trips, we compute a Pareto frontier to illustrate the time-energy tradeoff from driving different routes. We use Lagrangian relaxation to provide lower bounds and estimates that suggest that our algorithms produce near-optimal solutions. We apply our methodology to …

Multi-objective design optimization of a mobile-bearing total disc arthroplasty considering spinal kinematics, facet joint loads, and metal-on-polyethylene contact mechanics
… was determined by the solved three-dimensional Pareto frontier. The novel MOO framework can be also used to improve existing TDA designs, as well as to push the cutting edge of surgical techniques for the treatment of spinal disorders.</p>

Optimal pumping policy for a public supply wellfield using computational neural network with decision-making methodology
… different weight preferences. The resulting Pareto frontier served as the basis for multiobjective and conflict resolution analyses. The CNN and decision-making methodologies were then applied to a real-world test case in Toms River, New Jersey, where contaminated public supply wells, a …

Bayesian single- and multi- objective optimisation with nonparametric priors
… chapter 4. Here, one wishes to find a $\textit{Pareto frontier}$ of efficient settings with respect to several different objectives through sequential evaluation. Finally, in chapter 5 we exploit the idea that in a multi-objective setting, functions are $\textit{correlated}$, incorporating this …

Model use in sustainability negotiations and decisions
… In the first study, model users reached the Pareto Frontier-the set of non-dominated points-more readily (13%) than non-model-users (2.5%) and model users discovered the win-win nature of electricity access with higher frequency (63%) than non-model users (9%). Participants who learned of the …
