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 …

recorded by three-component very broadband seismometers at the stations Vitosha …

A note on lateral variation in upper mantle shear-wave velocity across the Alpine front

JA Rial, S Grand, DV Helmberger - Geophysical Journal …, 1984 - academic.oup.com
We have detected what appear to be strong lateral variations in upper mantle shear-wave
