Perhaps you should try some spelling variations:
"and computations using computer program" » "and computation using computer program" (Expand search), "and populations using computer program" (Expand search), "and computations in computer program" (Expand search), "and computational using computer program" (Expand search), "and competitions using computer program" (Expand search)
"using code to python programming" » "using cone to python programming" (Expand search), "using co to python programming" (Expand search), "using co2 to python programming" (Expand search), "using code tool python programming" (Expand search), "using code the python programming" (Expand search), "using code _ 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 computations using computer program\") OR (\"using code to python programming\"))~".
• Removing quotes may allow a broader search: (( and computations using computer program ) OR ( using code to python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computations using computer program") OR ("using code to python programming"))*.
