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.
Can the $n$-party broadcast channel, where any symbol sent by one party is received by all, be made resilient to noise with low overhead? Namely, is it possible to construct interactive error-correcting codes that convert any protocol designed for the noiseless broadcast channel into one that works over the noisy ... more >>>
In the standard model of computing multi-output functions in logspace ($\text{FL}$), we are given a read-only tape holding $x$ and a logarithmic length worktape, and must print $f(x)$ to a dedicated write-only tape. However, there has been extensive work (both in theory and in practice) on in-place algorithms for ... more >>>
Certification for Quantified Boolean Formulas (QBF) and Dependency Quantified Boolean Formulas is an ongoing challenge (DQBF). Recent proof complexity work has shown that the majority of QBF and DQBF techniques can be p-simulated by using the independent extension rule. In propositional logic, extension rules are supported by proof checkers using ... more >>>
