Perhaps you should try some spelling variations:
"based computation using subsampling program" » "based computation using sampling program" (Expand search), "based computational using subsampling program" (Expand search), "based competition using subsampling program" (Expand search), "based compilation using subsampling program" (Expand search), "based computations using subsampling program" (Expand search), "based computation in subsampling program" (Expand search), "based composition using subsampling program" (Expand search), "based computation and subsampling program" (Expand search)
"using tower python python programming" » "using tower pythons python programming" (Expand search), "using tower piton python programming" (Expand search), "using tower pitons python programming" (Expand search), "using the python python programming" (Expand search), "using tool python python programming" (Expand search), "using power python python programming" (Expand search), "using powered 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: "((\"based computation using subsampling program\") OR (\"using tower python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using subsampling program ) OR ( using tower python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using subsampling program") OR ("using tower python python programming"))*.
