• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coding multiobjective algorithm based\") OR (\"_ python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder coding multiobjective algorithm based ) OR ( _ python python python programming ))*.
