31 * The all variables full strong branching rule applies strong branching to every non-fixed variable
33 * which will cause the highest gain of the dual bound in the created sub-tree among all branching variables.
35 * For calculating the gain, a look-ahead is performed by solving the child node LPs which will result
38 * For a more mathematical description and a comparison between the strong branching rule and other branching rules
49 /*---+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0----+----1----+----2*/
69 * @return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref
72 * @note The variables in the lpcands array must have a fractional value in the current LP solution
