Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

open access: yesNetworks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.

Investigating Mixed‐Integer Programming Approaches for the p$$ p $$‐α$$ \alpha $$‐Closest‐Center Problem

open access: yesNetworks, EarlyView.
ABSTRACT In this work, we introduce and study the p$$ p $$‐α$$ \alpha $$‐closest‐center problem (pα$$ p\alpha $$CCP), which is a generalization of the p$$ p $$‐second‐center problem, a recently emerged variant of the classical (discrete) p‐center problem.

Interdiction Models and Heuristics for Graph Propagation

open access: yesNetworks, EarlyView.
ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

open access: yesOikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Analysis of the Crashworthiness of Novel Flax‐Fiber Hybrid Reinforced Three‐Dimensional Woven Composites

open access: yesPolymer Composites, EarlyView.
Through‐thickness binder yarns in tailored three‐dimensional woven flax‐fiber composites stabilize damage propagation and promote progressive crushing, enhancing crashworthiness and energy absorption. ABSTRACT This study investigates the impact crashworthiness performance of flax‐fiber reinforced three‐dimensional (3D) composites through a ...
