You may be able to get more results by adjusting your search query.

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