Abstract: Methods, network traffic manager apparatuses, non-transitory computer readable media, and systems that optimize a representation for detecting a pattern of a traffic flow are disclosed. The method includes retrieving a representation and dataset associated with the representation from storage and prompting a natural language processing model to transform the retrieved representation to a first candidate representation different than the retrieved representation based on the dataset. Then the method includes inputting the first candidate representation into a simulator to generate one or more first candidate metric values and evaluating whether to replace the retrieved representation with the first candidate representation based on the generated one or more first candidate metric values. This process may be iteratively implemented to optimize the generated candidate representation.
