Add an element to a SOS.

0 if function executed successfully, 1 otherwise

XPRBprob prob;
XPRBsos set1;
XPRBvar x2;
   ...
x2 = XPRBnewvar(prob, XPRB_PL," abc1",0 ,X PRB_INFINITY);
set1 = XPRBnewsos(prob, "sos1", XPRB_S1);
XPRBaddsosel(set1, x2, 9);

This adds a variable x2 with weight 9 to the SOS set1.

This function adds a single variable and its weight coefficient to a Special Ordered Set. If the variable is already contained in the set, the indicated value is added to its weight. Note that weight coefficients must be different from 0.

Note:

all members that are added to a SOS must belong to the same problem as the SOS itself.
