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