    • An Agent-Oriented Hierarchic Strategy for Solving Inverse Problems 

      Smolka M.; Schaefer R.; Paszynski M.; Pardo D.; Alvarez-Aramberri J. (International Journal of Applied Mathematics and Computer Science, 2015-12-31)
      The paper discusses the complex, agent-oriented hierarchic memetic strategy (HMS) dedicated to solving inverse parametric problems. The strategy goes beyond the idea of two-phase global optimization algorithms. The global ...
    • Dimensionally adaptive hp-finite element simulation and inversion of 2D magnetotelluric measurements 

      Alvarez-Aramberri J.; Pardo D. (Journal of Computational Science, 2016-09-01)
      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 three-dimensional (3D) ...
    • Multi-objective hierarchic memetic solver for inverse parametric problems 

      Gajda-Zagórska E.; Smolka M.; Schaefer R.; Pardo D.; Alvarez-Aramberri J. (Procedia Computer Science, 2015-12-31)
      We propose a multi-objective 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 multi-objective memetic inverse solver reinforced by local optimization methods 

      Gajda-Zagórska E.; Schaefer R.; Smołka M.; Pardo D.; Alvarez-Aramberri J. (Journal of Computational Science, 2016-09-01)
      We propose a new memetic strategy that can solve the multi-physics, complex inverse problems, formulated as the multi-objective optimization ones, in which objectives are misfits between the measured and simulated states ...
    • Quantities of interest for surface based resistivity geophysical measurements 

      Alvarez-Aramberri J.; Bakr S.A.; Pardo D.; Barucq H. (Procedia Computer Science, 2015-12-31)
      The objective of traditional goal-oriented 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 ...
    • Source time reversal (STR) method for linear elasticity 

      Brevis I.; Rodríguez-Rosas A.; Ortega J. H.; Pardo D. (Computers & Mathematics with Applications, 2018)
      We study the problem of source reconstruction for a linear elasticity problem applied to seismicity induced by mining. We assume the source is written as a variable separable function $\mathbf{f(x)}\>g(t)$ . We first present ...
