New and expanded chapters provide details of recently developed methods, such as the neighborhood algorithm, particle swarm optimization, hybrid Monte Carlo and multi-chain MCMC methods. Other chapters include new examples of applications, from uncertainty in climate modeling to whole earth studies. Several different examples of geophysical inversion, including joint inversion of disparate geophysical datasets, are provided to help readers design algorithms for their own applications. This is an authoritative and valuable text for researchers and graduate students in geophysics, inverse theory and exploration geoscience, and an important resource for professionals working in engineering and petroleum exploration.Geological modelingGeophysicsMathematical modelsInverse problems (Differential equations)Mathematical optimizationGeological modeling.GeophysicsMathematical models.Inverse problems (Differential equations)Mathematical optimization.550.1/515357SCI032000bisacshSen Mrinal K.1530569Stoffa Paul L.1948-UkCbUPUkCbUPBOOK9910792070103321Global optimization methods in geophysical inversion3775709UNINA
