"An early example of a symbolically discovered optimizer is that of Bengio et al. [8], who represent F as a tree: the leaves are the possible inputs to the optimizer (i.e. the xi above) and the nodes are one of {+, −, ×, ÷}. F is then evolved, making this an example of genetic programming [36]. Our search method is similar to genetic programming but we choose to represent the program as a sequence of instructions—like a programmer would type it—rather than a tree. "
