<a name="162651">Hello,<br><br>I want to understand weight of variables of SOS2 in the LP file in CPLEX. Could anyone explain "</a><a name="162651">Adjacency is defined by
the weights</a><a name="162651">" from the following sentence? Any kind of advice or comment is greatly appreciated.<br><br>Special ordered sets of type 2
require that at most two variables in the set may be non-zero, and if
there are two non-zeros, they must be adjacent. Adjacency is defined by
the weights, which must be unique within a set given to the variables.</a><br><br clear="all">Have a nice day!<br><br>Best,<br>Chendong<br>
