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