ARTIFICIAL INTELLIGENCE (AI) APPROACHES IN DRUG DISCOVERY: DEVELOPMENT AND VALIDATION OF NEW STRATEGIES IN VIRTUAL SCREENING CAMPAIGNS
… were developed and validated. FingerInt and HyperVolume are here proposed for enriching the pool of docking-derived descriptors, avoiding the multitude of ligand chemical descriptors, far away from the purpose of Explainable Artificial Intelligence (XAI).

Empirical Likelihood With Applications
… the Volume Under the ROC Surface (VUS) and the Hypervolume Under the ROC Manifold (HUM) measures, which are straight extensions of the Area Under the The Receiver Operating Characteristic (ROC) curve (AUC) for three-category and multi-category samples respectively. The popularity and importance …

Evolutionary Search Techniques with Strong Heuristics for Multi-Objective Feature Selection in Software Product Lines
… Hence it does better on the standard measures (hypervolume and spread) but it also generates far more products with 0 violations of domain constraints. We also present significant improvements to IBEA's performance by employing three strong heuristic techniques that we call PUSH, PULL, and …

Automating Pareto-Optimal Experiment Design via Efficient Bayesian Optimization
… batch selection strategy that optimizes for both hypervolume improvement and diversity of selected samples in order to efficiently advance promising regions of the Pareto front. Experiments on both synthetic test functions and real-world benchmark problems show that our algorithm predominantly …

A Metamodel based Multiple Criteria Optimization via Simulation Method for Polymer Processing
… of solutions dominated by the frontier using the hypervolume indicator. </p><p>In addition to the test problems and the simulation-based case studies, we applied the optimization method to two case studies where only experimental data was used. In these cases we molded the parts under study and …

Machine-assisted synthesis and development in pharmaceutical industry
… the reaction space based on the highest expected hypervolume improvement, algorithm-guided optimisation of eight continuous variables allowed for identification of the experimental Pareto front to account for the trade-offs between the reaction objectives conversion and yield. Then, expanding to …

Computational methods for multi-omic models of cell metabolism and their importance for theoretical computer science
… (including principal component analysis and hypervolume) to evaluate short term metabolic evolution and perform comparative analysis of metabolic conditions. On the other hand, my vision is that a biomolecular system can be cast as a “biological computer”, therefore providing insights into …

Evolutionary and genetic strategies for topology optimization of frameworks: pareto-comparisons and hybrid methods
… using three quality indicators: the hypervolume, epsilon and R indicators. The statistical significance of the quality indicators is also assessed. Again, two goals are used in this comparison: the maximum stress within the structure and the overall weight. Both hybrid methods can …

Utilizing an Integrated Approach to Explore Niche in a Complex Equatorial System
… formed Hutchinson’s n-dimensional niche hypervolume. The coexistence of species that utilize the same niche has been explained by a concept called ‘niche partitioning’, whereby species will differ in how they utilize resources (spatially, temporally or by the resources they acquire). …

Using metaheuristics with the ranking and selection indifference-zone procedure MMY in problems with many objectives
… of the resulting Pareto sets is assessed using hypervolume metrics and statistically compared using t-tests. Results shows that MMY-enhanced solutions are often statistically different and have lower hypervolumes due to the pruning of unsupported solutions. Despite the increased computational …

Simulation-based optimisation of public transport networks
… its performance relative to indicators like the hypervolume and spacing indicators as well as an analysis of the model's Pareto front. Lastly, a benchmarking of the model's performance when compared with other optimisation algorithms is carried out. After testing the so-called Simulation-based …

Investigating Reproductive Phenology and Alloparental Care in Leuciscid Fishes using Niche Theory Approaches
Mutualism is an understudied phenomenon across taxa, but is important to the persistence and structure of communities. The role of positive interactions in supporting threatened species is critically important given that freshwater fish are extremely vulnerable due to the combined effects of …
