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