Detailed Description
file reader for variable fixings
This reader allows to read a file containing fixation values for variables of the current problem. Each line of the file should have format
<variable name> <value to fix>
Note that only a subset of the variables may need to appear in the file. Lines with unknown variable names are ignored. The writing functionality is currently not supported.
- Note
- The format is equal to the (not xml) solution format of SCIP.
