Perhaps you should try some spelling variations:
"modeling computation using its program" » "modeling computational using its program" (Expand search), "modeling simulation using its program" (Expand search), "modeling notation using its program" (Expand search), "modeling computations using its program" (Expand search), "modeling computation in its program" (Expand search), "modeling composition using its program" (Expand search), "modeling computation using ats program" (Expand search), "modeling computation using units program" (Expand search), "modeling computation using bits programa" (Expand search), "modeling computation using item program" (Expand search), "modeling computation using in program" (Expand search), "modeling computation using icp program" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python 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 computation using its program") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modeling computation using its program\") OR (\"using python python python programming\"))".
• Removing quotes may allow a broader search: (( modeling computation using its program ) OR ( using python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("modeling computation using its program") OR ("using python python python programming"))*.
