SolFiles
Location to store intermediate solution files
| Type: | string | |
|---|---|---|
| Default value: | "" |
During the MIP solution process, multiple incumbent solutions are
typically found on the path to finding a proven optimal solution.
Setting this parameter to a non-empty string causes these solutions to
be written to files (in .sol format) as
they are found. The MIP solver will append _n.sol to the value
of the parameter to form the name of the file that contains solution
number 
. For example, setting the parameter to
value solutions/mymodel will create
files mymodel_0.sol, mymodel_1.sol, etc., in
directory solutions.
Note that intermediate solutions can be retrieved as they are
generated through a
callback (by requesting the
MIPSOL_SOL in a MIPSOL callback).
This parameter makes the process simpler.
Note: Only affects mixed integer programming (MIP) models
