    26 * @ingroup FILEREADERS
    27 * @brief file reader for variable fixings
    28 * @author Tobias Achterberg
    29 *
    30 * This reader allows to read a file containing fixation values for variables of the current problem. Each line of the
    31 * file should have format
    32 *
    33 * <variable name> <value to fix>
    34 *
    35 * Note that only a subset of the variables may need to appear in the file. Lines with unknown variable names are
    36 * ignored. The writing functionality is currently not supported.
    37 *
    38 * @note The format is equal to the (not xml) solution format of SCIP.
