Further information
1. This routine restores the data structures from the file
problem_name
.svf that was created by a previous execution of
XPRSsave (
SAVE). 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.
3. The use of the 'f' flag is not recommended and can cause unexpected results.
