The problem of finding a graceful labelling of a graph, or proving that the graph is not graceful, has previously been modelled as a CSP. A new and much faster CSP model of the pro...
The observation and modeling of natural Complex Systems (CSs) like the human nervous system, the evolution or the weather, allows the definition of special abilities and models re...

We address the new problem of puzzle layout as a new application of awing. We present two abstract models of puzzles, permutation puzzles and cyclic puzzles, which can be modeled a...
