A Multi-Start Biased-Randomized Algorithm for the Capacitated Dispersion Problem

open access: yesMathematics, 2022
The capacitated dispersion problem is a variant of the maximum diversity problem in which a set of elements in a network must be determined. These elements might represent, for instance, facilities in a logistics network or transmission devices in a ...

On the Use of Biased-Randomized Algorithms for Solving Non-Smooth Optimization Problems [PDF]

open access: yesAlgorithms, 2019
Soft constraints are quite common in real-life applications. For example, in freight transportation, the fleet size can be enlarged by outsourcing part of the distribution service and some deliveries to customers can be postponed as well; in inventory ...

The Stochastic Team Orienteering Problem with Position-Dependent Rewards

open access: yesMathematics, 2022
In this paper, we analyze both the deterministic and stochastic versions of a team orienteering problem (TOP) in which rewards from customers are dynamic. The typical goal of the TOP is to select a set of customers to visit in order to maximize the total

Using Biased-Randomized Algorithms for the Multi-Period Product Display Problem with Dynamic Attractiveness

open access: yesAlgorithms, 2020
From brick-and-mortar stores to omnichannel retail, the efficient selection of products to be displayed on store tables, advertising brochures, or online front pages has become a critical issue.

The Non-Smooth and Bi-Objective Team Orienteering Problem with Soft Constraints

open access: yesMathematics, 2020
In the classical team orienteering problem (TOP), a fixed fleet of vehicles is employed, each of them with a limited driving range. The manager has to decide about the subset of customers to visit, as well as the visiting order (routes).

Error Characteristics and Scale Dependence of Current Satellite Precipitation Estimates Products in Hydrological Modeling

open access: yesRemote Sensing, 2021
Satellite precipitation estimates (SPEs) are promising alternatives to gauge observations for hydrological applications (e.g., streamflow simulation), especially in remote areas with sparse observation networks.

A Biased-Randomized Iterated Local Search Algorithm for Rich Portfolio Optimization [PDF]

open access: yesApplied Sciences, 2019
This research develops an original algorithm for rich portfolio optimization (ARPO), considering more realistic constraints than those usually analyzed in the literature. Using a matheuristic framework that combines an iterated local search metaheuristic with quadratic programming, ARPO efficiently deals with complex variants of the mean-variance ...

A stacking ensemble algorithm for improving the biases of forest aboveground biomass estimations from multiple remotely sensed datasets

open access: yesGIScience & Remote Sensing, 2022
Accurately quantifying the aboveground biomass (AGB) of forests is crucial for understanding global change-related issues such as the carbon cycle and climate change.

Rethinking Artificial Intelligence: Algorithmic Bias and Ethical Issues| Questioning Artificial Intelligence: How Racial Identity Shapes the Perceptions of Algorithmic Bias

open access: yesInternational Journal of Communication, 2023
Growing concerns indicate that automated decision-making (ADM) may discriminate against certain social groups, but little is known about how social identities of people influence their perception of biased automated decisions. Focusing on the context of
