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