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

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