XPRBsync

---

Purpose

Synchronize BCL with the Optimizer.

Synopsis

int XPRBsync(XPRBprob prob, int synctype);

Arguments

prob	Reference to a problem.
synctype	Type of the synchronization. Possible values: XPRB_XPRS_SOL  update the BCL solution information with the solution currently held in the Optimizer; XPRB_XPRS_PROB  force problem reloading.

Return value

0 if function executed successfully, 1 otherwise.

Example

The following forces BCL to reload the matrix into the Optimizer even if there has been no change other than bound changes to the problem definition in BCL since the preceding optimization:

XPRBprob expl2;
expl2 = XPRBnewprob("example2");
 ...
XPRBsolve(expl2, "l");
 ...
XPRBsync(expl2, XPRB_XPRS_PROB);
XPRBsolve(expl2, "g");

Further information

1. This method resets the BCL problem status.

2. XPRB_XPRS_SOL: at the next solution access the solution information in BCL is updated with the solution held in the Optimizer (after MIP search: best integer solution, otherwise solution of the last LP solved).

3. XPRB_XPRS_PROB: at the next call to optimization or XPRBloadmat the problem is completely reloaded into the Optimizer; bound changes are not passed on to the problem loaded in the Optimizer any longer.
