abstract = "Lexicase selection achieves very good solution quality
by introducing ordered test cases. However, the
computational complexity of lexicase selection can
prohibit its use in many applications. we introduce
Batch Tournament Selection (BTS), a hybrid of
tournament and lexicase selection which is
approximately one order of magnitude faster than
lexicase selection while achieving a competitive
quality of solutions. Tests on a number of regression
datasets show that BTS compares well with lexicase
selection in terms of mean absolute error while having
a speed-up of up to 25 times. Surprisingly, BTS and
lexicase selection have almost no difference in both
diversity and performance. This reveals that batches
and ordered test cases are completely different
mechanisms which share the same general principle
fostering the specialization of individuals. This work
introduces an efficient algorithm that sheds light onto
the main principles behind the success of lexicase,
potentially opening up a new range of possibilities for
algorithms to come.",
