Perhaps you should try some spelling variations:
"using computations using subsampling program" » "using computations using sampling program" (Expand search), "using computational using subsampling program" (Expand search), "using computacional using subsampling program" (Expand search), "using imputation using subsampling program" (Expand search), "using computation using subsampling program" (Expand search), "using populations using subsampling program" (Expand search), "using computations in subsampling program" (Expand search), "using computations and subsampling program" (Expand search)
"using mobile python python programming" » "using mobile phone python programming" (Expand search), "using mobile pythons python programming" (Expand search), "using mobile piton python programming" (Expand search), "using mobile pitons 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 computations using subsampling program\") OR (\"using mobile python python programming\"))~".
• Removing quotes may allow a broader search: (( using computations using subsampling program ) OR ( using mobile python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computations using subsampling program") OR ("using mobile python python programming"))*.
