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