Claim 0:
1. A method for completing a hydraulic fracturing operation of a wellbore, the method comprising:
initiating a hydraulic fracturing plan that includes one or more surface variables of the hydraulic fracturing operation;
receiving diagnostics data of the hydraulic fracturing operation of the wellbore;
accessing a fracture formation model that models formation characteristics of fractures formed according to the hydraulic fracturing plan through the wellbore into a formation surrounding the wellbore during the hydraulic fracturing operation with respect to the one or more surface variables of the hydraulic fracturing operation;
selecting one or more subsurface objective functions from a plurality of subsurface objective functions for changing one or more of the formation characteristics of the fractures, the one or more subsurface objective functions including an objective function for cluster efficiency, the objective function for cluster efficiency including a number of clusters that have an on-target flow distribution throughout a plurality of clusters of perforations within a clustering stage and a number of clusters that have an over target flow relative to a total number of the clusters of perforations in the clustering stage;
maximizing the objective function for cluster efficiency by:
generating a sum by adding the number of clusters that have the on-target flow distribution to the number of clusters that have the over target flow, and
dividing the sum by the total number of the clusters of perforations in the clustering stage; and

applying the fracture formation model to update the hydraulic fracturing plan based on the diagnostics data to determine values of the one or more surface variables for controlling the formation characteristics of the fractures to converge on the one or more subsurface objective functions as the fractures are formed according to the updated hydraulic fracturing plan.
