problem.addcbafterobjective

Purpose
Declares a callback which will be called after each objective in a multi-objective problem is solved. This callback function will be called in addition to any callbacks already added by addcbafterobjective.
Synopsis

problem.addcbafterobjective(callback, data, priority)

callback(my_prob, my_object)
Arguments
callback 
The callback function which takes two arguments, my_prob and my_object, and has no return value. This function is called after every solve.
my_prob 
The problem passed to the callback function, callback.
my_object 
The user-defined object passed as data when setting up the callback with addcbafterobjective.
data 
A user-defined object to be passed to the callback function, callback.
priority 
An integer that determines the order in which multiple after objective callbacks will be invoked. The callback added with a higher priority will be called before a callback with a lower priority. Set to 0 if not required.
Example
This example logs a message after each objective is solved: 
def afterobjective(prob, object):
  print("Completed solve {}".format(prob.attributes.solvedobjs))

prob.addcbafterobjective(afterobjective, None, 0)
prob.optimize("")
