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