• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"applying computation using linear programming\") OR (\"using tool python python programming\"))".
• Removing quotes may allow a broader search: (( applying computation using linear programming ) OR ( using tool python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("applying computation using linear programming") OR ("using tool python python programming"))*.
