Perhaps you should try some spelling variations:
"coder formulation convex functions program" » "coder formulation coupled functions program" (Expand search), "coder formulation on functions program" (Expand search), "coder formulation under functions program" (Expand search), "powder formulation convex functions program" (Expand search), "model formulation convex functions program" (Expand search), "order formulation convex functions program" (Expand search), "coder formulation convex functional program" (Expand search), "coder formulation convex functional programs" (Expand search), "coder formulation convex function programac" (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: "((\"coder formulation convex functions program\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( coder formulation convex functions program ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder formulation convex functions program") OR ("using coding python python programming"))*.
