Tikhonov Regularization

When you select Tikhonov Regularization, the PEST control file will automatically be generated to support this feature.

 

Select the [Generate Tikhonov Regularization] button to select the type of regularization.

 

Preferred Homogenous (Smoothness): Prior information equations relate the pilot points to one another. Pilot points that are near one another should have close values; only enough heterogeneity will be introduced to the system as necessary, the level of the heterogeneity being controlled by the pertaining semi-variogram.

 

Preferred Value: Prior information equations relate the pilot points to their initial value. PEST will try to find a value that is as close to the initial pilot point value as possible.

 

 

 

 

 

 

When you are finished, proceed to the [Run PEST] step to begin the PEST run.
