Saves the current data structures, i.e. matrices, control settings and problem attribute settings to
file and terminates the run so that optimization can be resumed later.
The data structures are written to the file
problem_name.svf.
Optimization may recommence from the same point when the data structures are restored by a call to
XPRSrestore (
RESTORE). Under such
circumstances, the file
problem_name.sol and, if a branch and bound
search is in progress, the global files
problem_name.glb and
problem_name.ctp are also required. These files will be present
after execution of
XPRSsave (
SAVE), but will be modified by subsequent
optimization, so no optimization calls may be made after the call to
XPRSsave
(
SAVE). Note that the
.svf files created are particular to the release of the
Optimizer used to create them. They can only be read using the same release Optimizer as used to
create them.
