Short Description

Calculation of best approximation of geological structures using the Monte-Carlo method combined with iterative best approximation effort algorithm. The number of 3D spatial points may reach 500 M or more. Searching of best approximation points iteratively requires considerable processing power. The planned work aims to run the inversion algorithm in parallel systems and evaluate rates of convergence and of error for different iteration parameters. As first step the gravity field will be considered, with objective to repeat it for natural magnetic and electric fields. This would serve as basis for dealing more complex problems as induced currents (resistivity method) and induced polarization.
