setindicators

Purpose
Specifies that a set of rows in the matrix will be treated as indicator constraints, during a global search.
An indicator constraint is made of a condition and a linear constraint. The condition is of the type " bin = value", where bin is a binary variable and value is either 0 or 1. The linear constraint is any linear row. During global search, a row configured as an indicator constraint is enforced only when condition holds, that is only if the indicator variable bin has the specified value.
Synopsis
setindicators(
prob,
rowind,
colind,
complement,
nrows = x_max_vec_length(rowind, colind, complement)
)
Arguments
prob 
The current problem.
rowind 
Integer array of length nrows containing the indices of the rows that define the linear constraint part for the indicator constraints.
colind 
Integer array of length nrows containing the column indices of the indicator variables.
complement 
Integer array of length nrows with the complement flags:
0
not an indicator constraint (in this case the corresponding entry in the colind array is ignored);
1
for indicator constraints with condition " bin = 1";
-1
for indicator constraints with condition " bin = 0";
nrows 
The number of indicator constraints.
Return value
The input argument prob.
