Subject: [gecode-users] bin_packing with 0 item sizes

Hi,

In writing unit tests for ECLiPSe's Gecode interface, I noticed that for the
bin packing constraint, if an item size is 0, then its corresponding bin
variable is not constrained:

binpacking(home, l, b, s) where

b = {b1, b2}

s = {0, 1}

then b2 is constrained to [0,1], but b1's domain is not constrained (i.e.
has whatever the domain it was given).

Cheers,

Kish
