Hi Christian,
Thanks for this. I decided to change my code to ude INT_VAR_AFC_* with a
decay argument, and then I tried to rerun the test. However, I now get
a Gecode exception "AFC: Illegal decay factor" for a factor of 0.0 with
IntAFC afc(*solver, vars, 0.0);
while previously, I was able to set the decay factor to 0 with
afc_decay(0.0).
I assume this is because of a > vs >= test for the valid value. Should
this be changed? It seems 0 should be a legal value (even if it is not
too sensible).
On a related note, from the description in the MPG, I assume there is
only a single AFC decay factor, so setting the decay factor with
IntAFC afc(*solver, vars, decay)
will also change the "global" decay factor, i.e. the one obtained by
afc_decay(). Is this correct?
Cheers,
Kish
