1D Painless Multilevel Automatic GoalOriented h and p Adaptive Strategies Using a PseudoDual Operator
Caro, F.V.; Darrigrand, V.; AlvarezAramberri, J.; Alberdi, E.; Pardo, D. (20220101)The main idea of our GoalOriented Adaptive (GOA) strategy is based on performing global and uniform h or prefinements (for h and padaptivity, respectively) followed by a coarsening step, where some basis functions are ... 
An AgentOriented Hierarchic Strategy for Solving Inverse Problems
Smolka, M.; Schaefer, R.; Paszynski, M.; Pardo, D.; AlvarezAramberri, J. (20151231)The paper discusses the complex, agentoriented hierarchic memetic strategy (HMS) dedicated to solving inverse parametric problems. The strategy goes beyond the idea of twophase global optimization algorithms. The global ... 
Dimensionally adaptive hpfinite element simulation and inversion of 2D magnetotelluric measurements
AlvarezAramberri, J.; Pardo, D. (20160901)Magnetotelluric (MT) problems often contain different subdomains where the conductivity of the media depends upon one, two, or three spatial variables. Traditionally, when a MT problem incorporates a threedimensional (3D) ... 
$hp$Adaptive Simulation and Inversion of Magnetotelluric Measurements
AlvarezAramberri, J. (20151218)The magnetotelluric (MT) method is a passive exploration technique that aims at esti mating the resistivity distribution of the Earth’s subsurface, and therefore at providing an image of it. This process is divided into ... 
Magnetotelluric characterization of the alhama de murcia fault (Eastern Betics)  Preliminary results
Martí, A.; Queralt, P.; Ledo, J.J.; Marcuello, A.; AlvarezAramberri, J.; MartínezDíaz, J.J. (20161231)The Lorca Earthquake (11/5/2011, Mw 5.2) stands as the most destructive in Spain over the last 50 years. It was interpreted as having occurred in an intersegment zone of the strikeslip Alhama de Murcia Fault (AMF). Within ... 
Multiobjective hierarchic memetic solver for inverse parametric problems
GajdaZagórska, E.; Smolka, M.; Schaefer, R.; Pardo, D.; AlvarezAramberri, J. (20151231)We propose a multiobjective approach for solving challenging inverse parametric problems. The objectives are misfits for several physical descriptions of a phenomenon under consideration, whereas their domain is a common ... 
A multiobjective memetic inverse solver reinforced by local optimization methods
GajdaZagórska, E.; Schaefer, R.; Smolka, M.; Pardo, D.; AlvarezAramberri, J. (20160901)We propose a new memetic strategy that can solve the multiphysics, complex inverse problems, formulated as the multiobjective optimization ones, in which objectives are misfits between the measured and simulated states ... 
Quantities of interest for surface based resistivity geophysical measurements
AlvarezAramberri, J.; Bakr, S.A.; Pardo, D.; Barucq, H. (20151231)The objective of traditional goaloriented strategies is to construct an optimal mesh that minimizes the problem size needed to achieve a user prescribed tolerance error for a given quantity of interest (QoI). Typical ... 
A Secondary Field Based hpFinite Element Method for the Simulation of Magnetotelluric Measurements
AlvarezAramberri, J.; Pardo, D.; Barucq, E. (20151231)In some geophysical problems, it is sometimes possible to divide the subsurface resistivity distribution as a one dimensional (1D) contribution plus some two dimensional (2D) inhomogeneities. Assuming this scenario, we ... 
A Simulation Method for the Computation of the E
Omella, A. J.; AlvarezAramberri, J.; Strugaru, M.; Darrigrand, V.; Pardo, D.; Gonzalez, H.; Santos, C. (202103)We propose a set of numerical methods for the computation of the frequencydependent eff ective primary wave velocity of heterogeneous rocks. We assume the rocks' internal microstructure is given by microcomputed tomography ... 
Using Covariance Matrix Adaptation Evolutionary Strategy to boost the search accuracy in hierarchic memetic computations
Sawicki, J.; Los, M.; Smolka, M.; AlvarezAramberri, J. (201904)Many global optimization problems arising naturally in science and engineering exhibit some form of intrinsic illposedness, such as multimodality and insensitivity. Severe illposedness precludes the use of standard ...
