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