A note on the tight example in On the randomised query complexity of composition

Computational Complexity 2019-11-12 v2

Abstract

We make two observations regarding a recent tight example for a composition theorem for randomized query complexity: (1) it implies general randomized query-to-communication lifting is not always true if one allows relations, (2) it is in a certain sense essential that a relation is used in constructing the example.
