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)
"using rdf from python programming" » "using rdf from pathogen programming" (Expand search), "using rdf from anthony programming" (Expand search), "using rbf from python programming" (Expand search), "using rdna from python programming" (Expand search), "using raft from python programming" (Expand search), "using of from python programming" (Expand search), "using off from python programming" (Expand search), "using l.f from 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 (\"using rdf from python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computational using subsampling program ) OR ( using rdf from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational using subsampling program") OR ("using rdf from python programming"))*.
