Hi Kish,
I implemented the algorithm and it is the simple reason you mention. Perhaps we can port the Eclipse version into Gecode?

Subject: [gecode-users] algorithm used in sequence constraint
Hi,
In the MPG, it is stated that the sequence constraint is implemented
using the domain consistent algorithm described in the paper by van
Hoeve and others.
Last year, Helmut Simonis contributed the sequence constraint for
ECLiPSe, and he used the (also domain consistent) algorithm described in
the paper by Maher and others in CP 2008. As fat as I can tell from
checking the two papers, Maher's algorithm was developed after the one
proposed by van Hoeve, and may be more efficient.
Was the reason for implementing van Hoeve's algorithm in gecode simply
because it was made before Maher's was published, or is there some other
reason for picking it?
Thanks and cheers,
Kish
