Cosmological parameter estimation with Genetic Algorithms
Ricardo Medel-Esquivel, Isidro Gómez-Vargas, Alejandro A. Morales Sánchez +2
Genetic algorithms are a powerful tool in optimization for single and multi-modal functions. This paper provides an overview of their fundamentals with some analytical examples. In…
Neural network reconstructions for the Hubble parameter, growth rate and distance modulus
Isidro Gómez-Vargas, Ricardo Medel Esquivel, Ricardo García-Salcedo +1
This paper introduces a new approach to reconstruct cosmological functions using artificial neural networks based on observational measurements with minimal theoretical and statist…
A simple estimation of the size of the molecules using a pencil lead
Ricardo Medel-Esquivel, Isidro Gómez-Vargas, J. Alberto Vázquez +1
The main aim of this article is that students, at the basic level of education, gain a quantitative understanding of the size of molecules by performing a simple experiment easily…
