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

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