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