WRITEBINSOL
|
Purpose
Writes the current MIP or LP solution to a binary solution file for later input into the Optimizer.
Synopsis
int XPRS_CC XPRSwritebinsol(XPRSprob prob, const char *filename, const char *flags);
WRITEBINSOL [-flags] [filename]
Arguments
|
prob
|
The current problem.
|
|
filename
|
A string of up to 200 characters containing the file name to which the solution is to be written. If omitted, the default
problem_name is used with a .sol extension.
|
|
flags
|
Flags to pass to XPRSwritebinsol (WRITEBINSOL):
|
x
|
output the LP solution.

Example 1 (Library)
After an LP has been solved or a MIP solution has been found the solution can be saved to file.
If a MIP solution exists it will be written to file unless the -x flag is passed to XPRSwritebinsol (WRITEBINSOL)
in which case the LP solution will be written. The Optimizer input commands might then be:
XPRSreadprob(prob, "myprob", "");
XPRSmaxim(prob, "g");
XPRSwritebinsol(prob, "", "");
This reads in a matrix file, maximizes the MIP and saves the last found MIP solution.
Example 2 (Console)
An equivalent set of commands to the above for console users would be:
READPROB
MAXIM -g
WRITEBINSOL
