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