Problem Information, Optimizer
Synopsis
colind, complement = problem.getIndicators(first=0, last=ROWS-1)
Arguments
first 
First row in the range.
last 
Last row in the range (inclusive).
Return value
colind 
Integer array of length last-first+1 containing the column indices of the indicator variables.
complement 
Integer array of length last-first+1 containing the indicator 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".
Further information
1. This function cannot be called while the current problem is being solved or when it is in an interrupted state. Use problem.postSolve to restore the problem to a non-solving state.
2. Arguments first, last may contain xpress.constraint objects instead of indices.
