Finding sets of acceptable solutions with a genetic algorithm with application to surface wave group dispersion in Europe

A Lomax, R Snieder - Geophysical Research Letters, 1994 - Wiley Online Library
We discuss the use of a genetic algorithm (GA) to invert data for many acceptable solutions,
in contrast to inversion for a single,“optimum” solution. The GA is a directed search method …

Improved Monte Carlo inversion of surface wave data

LV Socco, D Boiero - Geophysical Prospecting, 2008 - earthdoc.org
Inversion of surface wave data suffers from solution non‐uniqueness and is hence strongly
biased by the initial model. The Monte Carlo approach can handle this non‐uniqueness by …

Monte-Carlo inversion for a global shear-velocity model of the crust and upper mantle

NM Shapiro, MH Ritzwoller - Geophysical Journal International, 2002 - academic.oup.com
We describe a method to invert surface wave dispersion data for a model of shear velocities
with uncertainties in the crust and uppermost mantle. The inversion is a multistep process …
