Perhaps you should try some spelling variations:
"based computational using sample problem" » "and computational using sample problem" (Expand search), "by computational using sample problem" (Expand search), "based computation using sample problem" (Expand search), "based computations using sample problem" (Expand search), "based computacional usinas sample problem" (Expand search), "based computational using complex problem" (Expand search), "based computational using same problems" (Expand search), "based computational using samples problem" (Expand search), "based computational using simple problem" (Expand search), "based computational using simplex problem" (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: "((\"based computational using sample problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using sample problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using sample problem") OR ("using coding python python programming"))*.
