Perhaps you should try some spelling variations:
"advanced computation using subsampling program" » "advanced computations using subsampling program" (Expand search), "advanced computational using subsampling program" (Expand search), "advance computational using subsampling program" (Expand search), "advanced computation using sampling program" (Expand search), "advanced computation in subsampling program" (Expand search), "advanced composition using subsampling program" (Expand search), "advanced computation 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 computation using subsampling program\") OR (\"mapping to python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using subsampling program ) OR ( mapping to python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using subsampling program") OR ("mapping to python python programming"))*.
