problem.loadDelayedRows

Purpose
Specifies that a set of rows in the matrix will be treated as delayed rows during a tree search. These are rows that must be satisfied for any integer solution, but will not be loaded into the active set of constraints until required.

Synopsis
problem.loadDelayedRows(rowind)
Argument
rowind 
An array of row indices to treat as delayed rows.
Further information
1. Delayed rows must be set up before solving the problem. Any delayed rows will be removed from the matrix after presolve and added to a special pool. A delayed row will be added back into the active matrix only when such a row is violated by an integer solution found by the Optimizer.
2. 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.
3. Argument rowind may contain xpress.constraint objects instead of indices.
