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