Journal ArticleDOI
On the subgraph epimorphism problem
TL;DR: The SEPIexistence problem is NP-complete by reduction of SAT and a constraint satisfaction algorithm is presented that has been successfully used to solve practical SEPIproblems on a large benchmark of reaction graphs from systems biology.
Book ChapterDOI
An Operational Model for the FIPA-ACL Semantics
Vincent Louis,Thierry Martinez +1 more
TL;DR: The formal principles supporting the FIPA-ACL semantics are reviewed and an operational model facilitating their implementation is proposed, resulting in more flexible agents, avoiding intensive use of rigid protocols.
Journal ArticleDOI
On enumerating minimal siphons in Petri nets using CLP and SAT solvers: theoretical and practical complexity
TL;DR: This paper shows that both the SAT and CLP methods are overall faster by one or two orders of magnitude compared to the state-of-the-art algorithm from the Petri net community, and are in fact able to solve all the enumeration problems of the practical benchmarks.
Proceedings ArticleDOI
On Solving Mixed Shapes Packing Problems by Continuous Optimization with the CMA Evolution Strategy
TL;DR: This work considers the covariance matrix adaptation evolution strategy (CMA-ES) with a non-overlapping and minimum size objective function in either two or three dimensions, and proposes other measures, monotonic with respect to the intersection area, to better guide the search.
Proceedings ArticleDOI
Semantics-preserving translations between linear concurrent constraint programming and constraint handling rules
TL;DR: Immediate consequences of this work include new proofs for CHR linear logic and phase semantics, relying on corresponding results for LCC, plus an encoding of the λ-calculus in CHR.
