Perhaps you should try some spelling variations:
"modeling computations using computer program" » "modeling computation using computer program" (Expand search), "modeling computational using computer program" (Expand search), "model computations using computer program" (Expand search), "modeling populations using computer program" (Expand search), "modeling computations in computer program" (Expand search)
"using coding modulo python programming" » "using coding model python programming" (Expand search), "using encoding module python programming" (Expand search), "using coding mode python programming" (Expand search), "using coding codigo python programming" (Expand search), "using coping modulo python programming" (Expand search), "using coating modulo python programming" (Expand search), "using cooking modulo 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: (("modeling computations using computer program") OR ("using coding modulo python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modeling computations using computer program\") OR (\"using coding modulo python programming\"))".
• Removing quotes may allow a broader search: (( modeling computations using computer program ) OR ( using coding modulo python programming )).
• Adding a wildcard symbol may retrieve word variants: (("modeling computations using computer program") OR ("using coding modulo python programming"))*.
