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