Convergence Analysis of Greedy Algorithms with Adaptive Relaxation in Hilbert Spaces
Pablo M. Berná, Andrea García
The Power-Relaxed Greedy Algorithm (PRGA) was introduced as a generalization of the so called Relaxed Greedy Algorithm, introduced by DeVore and Temlyakov, by replacing the relaxat…
Lebesgue-type estimates for greedy algorithms in quasi-Banach spaces
Miguel Berasategui, Pablo M. Berná, Hung Viet Chu +1
We continue the study of Lebesgue-type parameters for various greedy algorithms in quasi-Banach spaces. First, we introduce a parameter that can be used with the quasi-greedy param…
Approximation spaces, greedy classes and Lorentz spaces
Miguel Berasategui, Pablo M. Berná, Andrea García
We characterize the approximation spaces of a broad class of bases - which includes almost greedy bases - in terms of weighted Lorentz spaces. For those bases, we also find necessa…
Applying Evolutionary Metaheuristics for Parameter Estimation of Individual-Based Models
Antonio Prestes García, Alfonso Rodríguez-Patón
Individual-based models are complex and they have usually an elevated number of input parameters which must be tuned for reproducing the observed population data or the experimenta…
