                        If ties still exist across multiple Routes, matching precedence MUST be
                        determined in order of the following criteria, continuing on ties:


                        * The oldest Route based on creation timestamp.

Note that in case of ties the identity of the return value is not guaranteed.

  ```python
  import tensorflow as tf
  a = [1, 10, 26.9, 2.8, 166.32, 62.3]
  b = tf.math.argmax(input = a)
  c = tf.keras.backend.eval(b)
