We present constant-round interactive proof systems for sufficiently uniform versions of (mathcal{AC}^0[2]) and (mathcal{NC}^1). Both proof systems are doubly-efficient, and offer a better trade-off between the round complexity and the total communication than the work of Reingold, Rothblum, and Rothblum (STOC, 2016). Our proof system for (mathcal{AC}^0[2]) supports a more relaxed notion of uniformity and offers a better trade-off between the number of rounds and the round complexity that our proof system for (mathcal{NC}^1). We observe that all three aforementioned systems yield constant-round doubly-efficient proof systems for the All-Pairs Shortest Paths problem.
