Perhaps you should try some spelling variations:
"_ computational using subsampling program" » "_ computation using subsampling program" (Expand search), "_ computations using subsampling program" (Expand search), "_ computacional usinas subsampling program" (Expand search), "_ computational using sampling program" (Expand search), "_ computational and subsampling program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ computational using subsampling program") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ computational using subsampling program\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( _ computational using subsampling program ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ computational using subsampling program") OR ("using in python python programming"))*.
