It is worth to say that gecode spaces are a specialization of "mozart spaces" that are fine tunned for constraint programming. Both of them were designed by Christian: computation spaces in "oz-light" are the ones proposed in his PhD thesis and have been available in Mozart since the beginning.

Second we would also like to have the possibility of defining both search engines and branching strategies directly in Oz. That is very good for prototyping and to use specific problem information as heuristics right away. In conclusion we will do as much as possible to have the two ways available.

Great, that sounds very promising. 

Best wishes,
