Perhaps you should try some spelling variations:
"vector coding using convex programming" » "vector coding using cone programming" (Expand search), "vector coding using computer programming" (Expand search), "vector loading using convex programming" (Expand search), "vector modeling using convex programming" (Expand search), "vector drying using convex programming" (Expand search), "vector coding using context programming" (Expand search), "vector coding using complex programming" (Expand search)
"python python python python programming" » "pythons python pythons python programming" (Expand search), "piton python piton python programming" (Expand search), "pitons python pitons python programming" (Expand search)

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

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