Hi Kish, My bad... There is really no common basetype for search engines, the type I mentioned is actually for the implementations and not the interfaces...
I think you will have to wait until I have added a common basetype (there is a basetype, but it is not powerful enough), I might be able to do it until the end of the week. Sorry for the confusion!

I am not sure what class DFS is, but I can't see how it could be Engine*. Anway, I tried to do the assignment as you suggested: Search::Engine* segine; ... sengine = new DFS<GecodeSpace>(solver, o); and indeed I get the error cannot convert 'Gecode::DFS<GecodeSpace>*' to 'Gecode::Search::Engine*' (I first tried sengine = new DFS(solver, o) but got an error 'expected type-specifier') So I am not sure what to do -- do I need to change the type of sengine, and/or the way I assign an engine to sengine?
