Hello to all,
A question:
When I post a constraint on a solved space, it seems to be not
always propagated ... And this _not_always_ is what I am
worrying about - I want to know what is the rule. What I
mean is prety much like this:
---- code -----
int
get_weight(){
IntVar weight(this, 0, Limits::Int::int_max);
linear(this, this->vars, IRT_EQ, weight);
/*
this->status();
*/
return weight.val();
}
---- code -----
I invoke this function like
solved_space->get_weight()
from within the constrain() function (for BAB search).
Without the line
this->status();
I experienced assertion fault due to weight.max() !=
weight.min() : max, min remained the same as at the time of
initialization of weight.
Then I added the commented line and it worked fine.
But... I have another function I invoke on solved spaces,
which workes fine without the status() invocation.
What do I have to know about constraints on solved spaces?
Could you short explain, or give a hint for reading?
Thank you in advance for your support!
