Neglecting numerical stability issues, the computational cost of minimizing equations 12 is the same as the cost of minimizing the two objective functions in equation 9. Because several shots are encoded and directly imaged, the computational cost of this approach is considerably reduced relative to non-encoded (or single source) data sets. Equivalent formulations for conventional time-lapse seismic data sets have been shown by previous authors (Ajo-Franklin et al., 2005; Ayeni and Biondi, 2008).
