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