TFNP in the Random Oracle Model

Noah Fleming, Mika Göös, Ziyi Guan +7

We determine which major $\TFNP$ classes are hard in the random oracle model (ROM). Prior work establishes average-case hardness of highly structured subclasses of $\TFNP$ from str…

Spiky Rank and Its Applications to Rigidity and Circuits

Lianna Hambardzumyan, Konstantin Myasnikov, Artur Riazanov +2

We introduce spiky rank, a new matrix parameter that enhances blocky rank by combining the combinatorial structure of the latter with linear-algebraic flexibility. A spiky matrix i…

Sampling Permutations with Cell Probes is Hard

Yaroslav Alekseev, Mika Göös, Konstantin Myasnikov +2

Suppose we are given an infinite sequence of input cells, each initialized with a uniform random symbol from . How hard is it to output a sequence in that is close to…

Pseudodeterministic Communication Complexity

Mika Göös, Nathaniel Harms, Artur Riazanov +3

We exhibit an -bit partial function with randomized communication complexity but such that any completion of this function into a total one requires randomized commu…

Searching for Falsified Clause in Random (log n)-CNFs is Hard for Randomized Communication

Artur Riazanov, Anastasia Sofronova, Dmitry Sokolov +1

We show that for a randomly sampled unsatisfiable -CNF over variables the randomized two-party communication cost of finding a clause falsified by the given variable…

Equality is Far Weaker than Constant-Cost Communication

Mika Göös, Nathaniel Harms, Artur Riazanov

We exhibit an -bit communication problem with a constant-cost randomized protocol but which requires deterministic (or even non-deterministic) queries to an Equality…

Monotone Circuit Complexity of Matching

Bruno Cavalar, Mika Göös, Artur Riazanov +2

We show that the perfect matching function on -vertex graphs requires monotone circuits of size . This improves on the lower bound of Razbo…

Better Boosting of Communication Oracles, or Not

Nathaniel Harms, Artur Riazanov

Suppose we have a two-party communication protocol for which allows the parties to make queries to an oracle computing ; for example, they may query an Equality oracle. To t…

Resolution Over Linear Equations: Combinatorial Games for Tree-like Size and Space

Svyatoslav Gryaznov, Sergei Ovcharov, Artur Riazanov

We consider the proof system Res() introduced by Itsykson and Sokolov (Ann. Pure Appl. Log.'20), which is an extension of the resolution proof system and operates with disj…
