Perhaps you should try some spelling variations:
"advanced implementation and convex programming" » "advancing implementation and convex programming" (Expand search), "and implementation and convex programming" (Expand search), "based implementation and convex programming" (Expand search), "advanced implementation of convex programming" (Expand search), "advanced implementation and cone programming" (Expand search), "advanced implementation and computer programming" (Expand search), "advanced implementation in 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: "((\"advanced implementation and convex programming\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced implementation and convex programming ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced implementation and convex programming") OR ("using coding python python programming"))*.
