> Current implementation cannot handle some merge orders e.g., {0, 2, 1} in case of a test
case https://github.com/apache/incubator-hivemall/blob/97bc91247f1a453b6ffb49212800fa601d25c297/core/src/test/java/hivemall/evaluation/AUCUDAFTest.java#L207
> This should be refined, and AUC UDAF has to be able to compute and merge partial results
in an arbitrary order.
