Frank Stephan: A fast exponential time algorithm for Max Hamming Distance X3SAT
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, 24 October 2018, 17:00 hrs
Room: S17#0405, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: A fast exponential time algorithm for Max Hamming Distance X3SAT
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
SAT is the problem which asks whether a given list of clauses in
n Boolean variables can be satisfied by an assignment
to the variables which is common for all clauses,
XSAT is the variant of SAT which asks the same, but requires in
addition that in each clause exactly one literal is true; X3SAT
is the corresponding problem with the additional constraint that
every clause contains up to three literals only. continue reading…
Frank Stephan: Computational aspects of the hyperimmunefree degrees
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, 15 August 2018, 17:00 hrs
Room: S17#0405, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: Computational aspects of the hyperimmunefree degrees
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
A set A has hyperimmunefree degree, if every set B
Turing equivalent to A is already truthtable equivalent to A. continue reading…
Frank Stephan: Finitely generated semiautomatic groups
Update on the Logic Seminar at the National University of Singapore
(the originally announced speaker is ill and will speak on 12 April 2017)
Date: Wednesday, 22 March 2016, 17:00 hrs
Room: S17#0405, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: Finitely generated semiautomatic groups
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
The present work shows that Cayley automatic groups are semiautomatic
and exhibits some further constructions of semiautomatic groups. continue reading…
Frank Stephan: On block pumpable languages
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, Wednesday 10 Aug 2016, 17:00 hrs
Room: S17#0405, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: On block pumpable languages
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
Abstract:
Call a language L block pumpable iff there is a constant p>1 such
that for every splitting of a word in the language L into p+1 blocks,
one can find a subword consisting of an interval of the interior blocks
such that each modified word obtained by repeating or omitting this
subword is also in the language L. continue reading…
Frank Stephan: Learning automatatic families of languages
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, 9 March 2016, 17:00 hrs
Room: S17#0511, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: Learning automatatic families of languages
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
A class of languages is automatic if it is uniformly regular
using some regular index set for the languages. continue reading…
Frank Stephan: The complexity of semiautomatic structures
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, 21 October 2015, 17:00 hrs
Room: S17#0406, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: The complexity of semiautomatic structures
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
Abstract:
This talk extends previous work on semiautomatic structures and in
particular investigates complexity issues with groups and semigroups;
furthermore, results from recursion theory are used to show that one
specific structure is not semiautomatic while a related one can be
shown to be semiautomatic. continue reading…

Frank Stephan: Automatic Structures – recent results and open questions
Invitation to the Logic Seminar at the National University of Singapore
Date: Wednesday, 25 March 2015, 17:00 hrs
Room: S17#0511, Department of Mathematics, NUS
Speaker: Frank Stephan
Title: Automatic Structures – recent results and open questions
URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html
Abstract:
Automatic structures are a way to represent algebraic
structures using finite automata; all the algebraic operations
and relations have to be recognised / verified by finite automata
which read the inputs and outputs with the same speed (one symbol
per cycle). continue reading…
