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