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

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