Perhaps you should try some spelling variations:
"using computation using subsampling program" » "using computation using sampling program" (Expand search), "using computational using subsampling program" (Expand search), "using imputation using subsampling program" (Expand search), "using compilation using subsampling program" (Expand search), "using computations using subsampling program" (Expand search), "using computation in subsampling program" (Expand search), "using composition using subsampling program" (Expand search), "using computation and subsampling program" (Expand search)
"using map coding python programming" » "using map codigo python programming" (Expand search), "using map codigos python programming" (Expand search), "using map using python programming" (Expand search), "using maps coding python programming" (Expand search), "using map encoding python programming" (Expand search), "using map3k coding python programming" (Expand search), "using mass coding python programming" (Expand search), "using mask coding python programming" (Expand search), "using mean coding 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 computation using subsampling program\") OR (\"using map coding python programming\"))~".
• Removing quotes may allow a broader search: (( using computation using subsampling program ) OR ( using map coding python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation using subsampling program") OR ("using map coding python programming"))*.
