resistivity by utilizing theoretical EMF and measured EMF. In this work, very fast simulated annealing (VFSA) that could obtain the global optimal solution is chosen as the fitting algorithm and TEM late time apparent resistivity is used to confirm the scope of the initial model. Simulated annealing stems from statistical thermal physics. It stimulates the process that objects gradually cool down......
