An Extended Formulation With Valid Inequalities for the Capacitated Steiner Arborescence Problem
Networks, EarlyView.ABSTRACT Given a directed graph, the Capacitated Steiner Arborescence Problem (CSAP) aims to determine the least‐cost connection from the root node to terminal nodes requiring a demand through Steiner nodes coming with a capacity, such that there is a unique path from the root to each terminal. This paper presents a new extended formulation of the CSAP,

Connecting the distribution and diversification of marine plants
Oikos, EarlyView.Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them
People and Nature, EarlyView.Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

International Economic Review, 2014 AbstractOften, numerical simulations for dynamic, stochastic models in economics are needed. Kim et al. (Journal of Economic Dynamics and Control 32 2008, 3397–414) proposed “pruning” to deal with the challenge of generating explosive paths when employing second‐order approximations.

The concept of dominance among nodes of a branch-and-bound tree, although known for a long time, is typically not exploited by general-purpose mixed-integer linear programming (MILP) codes. The starting point of our work was the general-purpose dominance procedure proposed in the 1980s by Fischetti and Toth, where the dominance test at a given node of

To prune or not to prune; pruning induced decay in tropical sandalwood
Forest Ecology and Management, 2018Abstract Heartwood rot (a fungal disease) has the potential to significantly reduce the sandalwood oil production of Santalum album. With new plantations being established with sandalwood oil as the major product, it is imperative to know the consequences of routine form-pruning in tropical areas. Examining pruning wound responses in 1 and 5-year-old

DivPrune: Diversity-based Visual Token Pruning for Large Multimodal Models
Computer Vision and Pattern RecognitionLarge Multimodal Models (LMMs) have emerged as powerful models capable of understanding various data modalities, including text, images, and videos. LMMs encode both text and visual data into tokens that are then combined and processed by an integrated ...

ThinkPrune: Pruning Long Chain-of-Thought of LLMs via Reinforcement Learning
Trans. Mach. Learn. Res.We present ThinkPrune, a simple yet effective method for pruning the thinking length for long-thinking LLMs, which has been found to often produce inefficient and redundant thinking processes. Existing preliminary explorations of reducing thinking length
