Aaron Potechin#### Bounds on Monotone Switching Networks for Directed Connectivity

Revisions: 1

Boaz Barak, Samuel Hopkins, Jonathan Kelner, Pravesh Kothari, Ankur Moitra, Aaron Potechin

We prove that with high probability over the choice of a random graph $G$ from the Erd\H{o}s-R\'enyi distribution $G(n,1/2)$, the $n^{O(d)}$-time degree $d$ Sum-of-Squares semidefinite programming relaxation for the clique problem will give a value of at least $n^{1/2-c(d/\log n)^{1/2}}$ for some constant $c>0$.

This yields a nearly tight ...

We prove tight size bounds on monotone switching networks for the NP-complete problem of

$k$-clique, and for an explicit monotone problem by analyzing a pyramid structure of height $h$ for

the P-complete problem of generation. This gives alternative proofs of the separations of m-NC

from m-P and of m-NC$^i$ from ...

We prove that any monotone switching network solving directed connectivity on $N$ vertices must have size $N^{\Omega(\log N)}$
