Ordered Semiautomatic Rings with Applications to Geometry

no code implementations11 Mar 2021 ZiYuan Gao, Sanjay Jain, Ji Qi, Philipp Schlicht, Frank Stephan, Jacob Tarr

The present work looks at semiautomatic rings with automatic addition and comparisons which are dense subrings of the real numbers and asks how these can be used to represent geometric objects such that certain operations and transformations are automatic.

Improved Algorithms for the General Exact Satisfiability Problem

no code implementations21 Jan 2021 Gordon Hoi, Frank Stephan

The Exact Satisfiability problem asks if we can find a satisfying assignment to each clause such that exactly one literal in each clause is assigned $1$, while the rest are all assigned $0$.

Algorithmic learning of probability distributions from random data in the limit

no code implementations31 Oct 2017 George Barmpalias, Frank Stephan

We study the problem of identifying a probability distribution for some given randomly sampled data in the limit, in the context of algorithmic learning theory as proposed recently by Vinanyi and Chater.
