An Evaluation of Landmark-Based Methods to Explore Tooth Score Morphology: A Case Study on Felids and Hyenids
(MDPI, 2023-03-17)Taphonomic studies aim to identify the modifying agents that intervene in bone assemblages found at archaeopaleontological sites. Carnivores may modify, accumulate, or scavenge skeletal parts inflicting tooth marks, including ... -
An Evaluation of Methods for Estimating the Number of Local Optima in Combinatorial Optimization Problems
Hernando Rodríguez, Leticia; ; (MIT Press, 2013-11-01)
[EN] The solution of many combinatorial optimization problems is carried out by metaheuristics, which generally make use of local search algorithms. These algorithms use some kind of neighborhood structure over the search ... -
An Exact Approach to Elimination of Leakage in a Qubit Embedded in a Three-level System
(Nature, 2019-07-30)Leakage errors damage a qubit by coupling it to other levels. Over the years, several theoretical approaches to dealing with such errors have been developed based on perturbation arguments. Here we propose a different ... -
