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 lambda python python programming" » "using lambda pythons python programming" (Expand search), "using lambda piton python programming" (Expand search), "using lambda pitons python programming" (Expand search), "using lamb python python programming" (Expand search), "single lambda python python programming" (Expand search), "using lambert 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: (("using computational using subsampling program") OR ("using lambda python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational using subsampling program\") OR (\"using lambda python python programming\"))".
• Removing quotes may allow a broader search: (( using computational using subsampling program ) OR ( using lambda python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computational using subsampling program") OR ("using lambda python python programming"))*.
