Perhaps you should try some spelling variations:
"and computation using computer program" » "and computations using computer program" (Expand search), "and computation in computer program" (Expand search), "and composition using computer program" (Expand search), "and computational using computer program" (Expand search), "of computation using computer program" (Expand search)
"using coding 2d python programming" » "using coping 2d python programming" (Expand search), "using coating 2d python programming" (Expand search), "using cooking 2d python programming" (Expand search), "using coding 3d python programming" (Expand search), "using coding and python programming" (Expand search), "using coding _ python programming" (Expand search), "using coding 3d vpython programming" (Expand search), "using coding mda 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 computer program\") OR (\"using coding 2d python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using computer program ) OR ( using coding 2d python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using computer program") OR ("using coding 2d python programming"))*.
