On the Complexity of Language Membership for Probabilistic Words
Antoine Amarilli, Mikaël Monet, Paul Raphaël +1
We study the membership problem to context-free languages (CFLs) on probabilistic words, that specify for each position a probability distribution on the letters. Our task is to co…
Tractable Gap-Constraint Languages for Complex Event Recognition
Antoine Amarilli, Florin Manea, Tina Ringleb +1
For strings , a subsequence embedding of in is a function with for every $i \in \{…
Gray Codes With Constant Delay and Constant Auxiliary Space
Antoine Amarilli, Claire David, Nadime Francis +3
We give the first two algorithms to enumerate all binary words of (like Gray codes) while ensuring that the delay and the auxiliary space is independent from ,…
Tighter Bounds for Query Answering with Guarded TGDs
Antoine Amarilli, Michael Benedikt
We consider the complexity of the open-world query answering problem, where we wish to determine certain answers to conjunctive queries over incomplete datasets specified by an ini…
Out-of-Order Membership in Regular Languages
Antoine Amarilli, Sebastien Labbe, Charles Paperman
We introduce the task of out-of-order membership to a formal language L, where the letters of a word w are revealed one by one in an adversarial order. The length |w| is known in a…
The S-Hamiltonian Cycle Problem
Antoine Amarilli, Arthur Lombardo, Mikaël Monet
Determining if an input undirected graph is Hamiltonian, i.e., if it has a cycle that visits every vertex exactly once, is one of the most famous NP-complete problems. We consider…
