XPRSloaddelayedrows

XPRSloaddelayedrows

Purpose
Specifies that a set of rows in the matrix will be treated as delayed rows during a global 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
int XPRS_CC XPRSloaddelayedrows(XPRSprob prob, int nrows, const int mrows[]);
Arguments
prob 
The current problem.
nrows 
The number of delayed rows.
mrows 
An array of row indices to treat as delayed rows.
Example
This sets the first six matrix rows as delayed rows in the global problem prob. 
int mrows[] = {0,1,2,3,4,5}
...
XPRSloaddelayedrows(prob,6,mrows);
XPRSmipoptimize(prob,"");
Further information
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.
