One path crosses the Guerrero terrane while the other traverses theOaxaca terrane. The dispersion curves have been inverted for crustal structure using genetic and simulated annealing algorithms.Our results show significant differences in crustal structure beneath the Guerrero and the Oaxaca terranes, especially in velocity ofthe superficial layer and Moho depth. The genetic algorithm (GA) is considerably faster than the simulated annealing algorithm(SA). On the other hand, the SA requires a small computer memory. Another significant advantage of SA is that it reaches asmaller misfit value than GA. 2001 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56840303 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.40 |
