Perhaps you should try some spelling variations:
"based computational and subsampling program" » "and computational and subsampling program" (Expand search), "by computational and subsampling program" (Expand search), "based computational and sampling program" (Expand search), "based computational fluid subsampling program" (Expand search), "based computational using subsampling program" (Expand search)
"using tool python python programming" » "using tool pythons python programming" (Expand search), "using tool piton python programming" (Expand search), "using tool pitons python programming" (Expand search), "using tools python python programming" (Expand search), "using total python python programming" (Expand search), "using tonal 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 computational and subsampling program\") OR (\"using tool python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational and subsampling program ) OR ( using tool python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational and subsampling program") OR ("using tool python python programming"))*.
