The final, definitive version of this document can be found online at Geophysics, published by Society of Exploration Geophysicists. IE inversion algorithm lead to satisfactory inversion models for both synthetic and real cases which reconstruct the subsurface better than or as well as that of the software.This is an author-produced, peer-reviewed version of this article. Finally, the algorithm is applied on an archeological data set of Pompeii, which was collected by dipole-dipole array. Three synthetic data sets computed by Res2dmod software are utilized to investigate the performance of the algorithm through comparing the results with Res2dinv software output sections. What is the method in the RES2Dinv software (Loke) that give the best results for the L1 or L2 norm RES2Dinv software : L1 or L2 norm. (2001), but here in addition to improving results for dipole-dipole array, its productivity is demonstrated for other geo-electrical arrays such as Wenner alfa, Wenner Schlumberger. The presented technique was used only for dipole-dipole array by Perez-Flores et al. Inversion algorithm is iterative and regularization parameter and depth weighting exponent are the critical parameters that have default values of 0.1 and 1, respectively. This very popular software, developped by M.H.Loke, uses the method involving the Sasaki minimum squares inversion (1992) to produce a 2D sub-soil model.

We took the advantage of the 2-D forward operator formula obtained based on integral equations (IE) by Perez- Flores et al. Scribd is the worlds largest social reading and publishing site. Inversion procedure is linear however, DC resistivity data inversion is generally nonlinear due to the nonlinearity of Maxwell’s equation relative to resistivity (conductivity). 3.50, Rapid 2-D Resistivity and IP Inversion Using the Least Square Method, Geotomo Software, Penang, 2002. 'So they will contest in those,' he said.
In this paper, a new simple, efficient and semi-automatic algorithm including depth weighting constraint is introduced for 2-D DC resistivity data inversion. Loke said while they have not counted the number of seats, Penang has 19.
