• Performing a fuzzy search may retrieve terms with similar spellings: (("modeling computation to precoder program") OR ("using using python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modeling computation to precoder program\") OR (\"using using python python programming\"))*".
• Removing quotes may allow a broader search: (( modeling computation to precoder program ) OR ( using using python python programming ))*.
