• #### An Agent-Oriented Hierarchic Strategy for Solving Inverse Problems ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ...
• #### Propagation of 1D Waves in Regular Discrete Heterogeneous Media: A Wigner Measure Approach ﻿

(2014-12-31)
In this article, we describe the propagation properties of the one-dimensional wave and transport equations with variable coefficients semi-discretized in space by finite difference schemes on non-uniform meshes obtained ...
• #### Quantities of interest for surface based resistivity geophysical measurements ﻿

(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 ﻿

(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 ...
