Metaheuristics in Logistics: Increasing the Efficiency of Algorithms by Defining Appropriate Parameter Settings
Published 2024-12-01“…They are extremely problem- and parameter-sensitive methods, so the exact definition of the necessary data and the testing of the appropriate parameters fundamentally determine the efficiency and performance of an algorithm. This is a time-consuming and expensive task. In many cases, when applying a metaheuristic, it works properly with the variables of a given task and there is no specific interval where a given algorithm can still be effective. …”

Manières de voir, manières de faire : moderniser les canaux gravitaires
Published 2021-10-01“…In the South of France, gravity-fed irrigation canals embody centuries-old experience in water management in response to the high variability of rainfall across space and time. But nowadays, the sustainability of these works (called "béals" in the Cévennes gardoises) is no longer given and their very existence comes in the way of the adaptation to the new regulations concerning water sharing and quality (water laws 1992, 2006). …”
