Perhaps you should try some spelling variations:
"using computational using subsampling program" » "and computational using subsampling program" (Expand search), "using computation using subsampling program" (Expand search), "using computations using subsampling program" (Expand search), "using computacional usinas subsampling program" (Expand search), "using computational using sampling program" (Expand search), "using computational and subsampling program" (Expand search)
"using mobile pym python programming" » "using mobile pre python programming" (Expand search), "using mobile bim python programming" (Expand search), "using mobile pytm 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 computational using subsampling program\") OR (\"using mobile pym python programming\"))~".
• Removing quotes may allow a broader search: (( using computational using subsampling program ) OR ( using mobile pym python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational using subsampling program") OR ("using mobile pym python programming"))*.
