1. This routine restores the data structures from the file
problem_name.svf that was
created by a previous execution of
XPRSsave (
SAVE). The file
problem_name.sol is also
required and, if recommencing optimization in a global search, the files
problem_name.glb and
problem_name.ctp are required too. Note that
.svf files
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.
2. (
Console) The main use for
XPRSsave
(
SAVE) and
XPRSrestore (
RESTORE) is to enable the user
to interrupt a long optimization run using CTRL-C, and save the Optimizer status with the ability to
restart it later from where it left off. It might also be used to save the optimal status of a
problem when the user then intends to implement several uses of
XPRSalter
(
ALTER) on the problem, re-optimizing each time from the saved status.
