class_docstr: The parameter offload solver.
  
  Args:
      region_list (List[Region]): represents the linearized DNN computing graph.
      memory_budget (float): the given memory budget.
      error_factor (float): the error factor.
          It is used to reduce the memory budget. Due to some errors in the estimation of peak memory and execution time.
docstr: Compare the profits of the two offload strategies using the dictionary order algorithm.
  
  Args:
      profit_a (tuple): the profit of a offload strategy.
      profit_b (tuple): the profit of another offload strategy.
  
  Returns:
      bool: whether profit_a is greater than profit_b.
