Perhaps you should try some spelling variations:
"code computational using integer programming" » "code computation using integer programming" (Expand search), "code computations using integer programming" (Expand search), "code computacional usinas integer programming" (Expand search), "code computational using linear programming" (Expand search), "model computational using integer programming" (Expand search), "cfd computational using integer programming" (Expand search), "some computational using integer programming" (Expand search), "code computational using inter programming" (Expand search), "code computational using internet programming" (Expand search), "code computational using integral programming" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"code computational using integer programming\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( code computational using integer programming ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("code computational using integer programming") OR ("using codigo python python programming"))*.
