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

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