I don't agree
I have not said that it should "be copied" illegally
I have said that many programs improved after "FRUIT" liberates its code, (for example) and before this engine other many were published... (single John von Neumann has the sole right... ; -))
the way that the algorithms and search systems find improved it is due to the work of "some" people.
it is something like that as "windows" "linux"... close codig, open source.
from the same moment that some tricks are commented" used by some program (including the fact of showing the search depth INCORRECTLY, with the simple one made of masking the evaluation of this-that engine... rrrr....)
from that same moment the improvements will be been of a logical EVOLUTION for that? ... for that perhaps code portions can be imprisoned... but the ideas are free and they can be implemented in a different way...
soon will "happen" evident changes...
bye, since Spain.
