An AgentOriented Hierarchic Strategy for Solving Inverse Problems
(International Journal of Applied Mathematics and Computer Science, 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
(Journal of Computational Science, 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) ... 
Multiobjective hierarchic memetic solver for inverse parametric problems
(Procedia Computer Science, 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
(Journal of Computational Science, 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
(Procedia Computer Science, 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 ... 
Source time reversal (STR) method for linear elasticity
(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 ...
