[gecode-users] Removing propagators from a Space

[Christian Schulte]

Removing all is easy and useful. Removing some is a pain in the .

 

I'll do the former.

That would be cool.
I think it is not useful for the normal use of GeCode, so you have to decide
if you want to bloat your code with this.
But I would appreciate it.
If there would be also the possibility to only remove certain constraints,
that would be even more awesome.
But here I see why it is difficult, as Propagators would need to be
identified by something.


Best,
Max

But I could add it for Gecode 4.*, should not be that hard. Do you want it?

No, that's currently not supported.  You'll have to work around it as you
suggested.

 

Cheers,

Is there a way to remove all propagators from a space "a".
In this way the space contains only the restricted variables so far but
no constraints on them.
I need such a space and i want to avoid creating an empty space "b" and
adding all variables and constraining them to the values they had in "a".


Is this possible?


Best,
Max
