Hello all,How are you doing? I know that Gecode is not made for concurrent constraint programming and there are not combinators in Gecode. But, since the ask propagator worked very good. Now I am interested in writting the parallel conditional combinator in Gecode. Not necessary as a combinator, but I need something with this semantic:
Non deterministically choose if Boolean var 1 then Process 1 if Boolean var 2 then Process 2 if Boolean var n then Process n end >From the n variables, I want to execute choose one process between the variables which value is assigned true. Since, it is not possible to write non-monotonic propagators in Gecode, what can I do? I tried doing the choice, after I reach a fix-point, but what happens if I have many of this non-deterministic choices? It is required to write it this using Gecode and being efficient. All ideas are welcomed. Thanks P.S : Gecode developers, do you want to include the ask propagator inside Gecode? I have an stress example showing better performance than using Mozart-Oz.
