Comparison between interactive (subjective) and traditional (numerical) inversion by Genetic Algorithms

چکیده
Inversion algorithms employ numerical evaluation of the mismatch between model and data to guide the search for minima in parameter spaces. In an alternative approach, the numerical evaluation of data misfit can be replaced by subjective judgement of the solution quality. This widens the class of problems that can be treated within the framework of formal inverse theory, in particular including various applications in which “structural similarity” between model and data determines the quality of the fit. In this paper we compare the performance of a traditional numerical inversion with an interactive inversion, in which a priori knowledge, experience and even personal intuition are provided by the user via subjective jugement. The comparison is performed on a geological application and shows that user expertise can partly compensate for lack of sufficient constraints in the numerical inversion.

A New Approach to Solve N-Queen Problem with Parallel Genetic Algorithm
Over the past few decades great efforts were made to solve uncertain hybrid optimization problems. The n-Queen problem is one of such problems that many solutions have been proposed for. The traditional methods to solve this problem are exponential in terms of runtime and are not acceptable in terms of space and memory complexity. In this study, parallel genetic algorithms are proposed to solve...
متن کاملA new stochastic 3D seismic inversion using direct sequential simulation and co-simulation in a genetic algorithm framework
Stochastic seismic inversion is a family of inversion algorithms in which the inverse solution was carried out using geostatistical simulation. In this work, a new 3D stochastic seismic inversion was developed in the MATLAB programming software. The proposed inversion algorithm is an iterative procedure that uses the principle of cross-over genetic algorithms as the global optimization techniqu...
