About the ECCC

What we do and why

The Electronic Colloquium on Computational Complexity (ECCC) was established in 1994 as a forum and repository for the rapid and widespread interchange of ideas, techniques, and research in computational complexity. Posting on the ECCC has the status of a technical report. The Electronic Colloquium on Computational Complexity welcomes papers, short notes, and surveys, with
  • relevance to the theory of computation,
  • clear mathematical profile, and
  • strictly mathematical format.

Central topics

  • models of computation and their complexity.
  • complexity bounds and trade-offs (with the emphasis on lower bounds).
  • complexity theoretic aspects of specific areas including coding theory, combinatorics, cryptography, game theory, logic, machine learning, optimization, property testing, and quantum computation.
For more details see the Call for Papers.

Service Interruption

In the last few days, a Denial of Service attack was launched on universities in Israel, leading the administrators of the Israel Academic network to block access to it from the global internet. Consequently, websites such as ECCC have been accessible only from within the Israeli and European academic networks.

It seems that this blocking was just removed, and we hope it will not be put back in the future.

Needless to say, deciding on such blocking is not in our control, but we do apologize for this disruption of service.

Pseudorandomness Beating the Hybrid Argument for Insensitive Algorithms

The hardness vs. randomness paradigm converts a function $f \colon \{0,1\}^n \rightarrow \{0,1\}$ that is hard for circuits of size $s$ into a pseudorandom generator (PRG) $G \colon \{0,1\}^d \to \{0,1\}^{s'}$ that fools circuits of size $s' = s'(s)$. In the application for derandomization, such as proofs of $\mathbf{BPP} = ... more >>>

Hard-to-Sample Distributions from Robust Extractors

We provide a unified method for constructing explicit distributions which are difficult for restricted models of computation to generate. Our constructions are based on a new notion of robust extractors, which are extractors that remain sound even when a small number of points violate the min-entropy constraint. Using such objects, ... more >>>

Maximum Matching and Related Problems in Catalytic Logspace

Understanding the power of space-bounded computation with access to catalytic space has been an important theme in complexity theory over the recent years. One of the key algorithmic results in this area is that bipartite maximum matching can be computed in catalytic logspace with a polynomial-time bound, Agarwala and Mertz ... more >>>
