Perhaps you should try some spelling variations:
"using computation time convex programming" » "using computation time cone programming" (Expand search), "using computation time computer programming" (Expand search), "using computational time convex programming" (Expand search), "using imputation time convex programming" (Expand search), "using compilation time convex programming" (Expand search), "using computation the convex programming" (Expand search), "using computation tree convex programming" (Expand search), "using computation time context programming" (Expand search), "using computation some convex programming" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking python python programming" (Expand search)

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

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