Perhaps you should try some spelling variations:
"based computation using computer program" » "based computational using computer program" (Expand search), "based competition using computer program" (Expand search), "based compilation using computer program" (Expand search), "based computations using computer program" (Expand search), "based computation in computer program" (Expand search), "based composition using computer program" (Expand search)
"using mobile base python programming" » "using mobile based python programming" (Expand search), "using mobile phase python programming" (Expand search), "using mobile laser python programming" (Expand search), "using mobile gate python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based computation using computer program") OR ("using mobile base python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using computer program\") OR (\"using mobile base python programming\"))".
• Removing quotes may allow a broader search: (( based computation using computer program ) OR ( using mobile base python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation using computer program") OR ("using mobile base python programming"))*.
