Perhaps you should try some spelling variations:
"modeling computation using act program" » "modeling computational using act program" (Expand search), "modeling simulation using act program" (Expand search), "modeling notation using act program" (Expand search), "modeling computations using act program" (Expand search), "modeling computation in act program" (Expand search), "modeling composition using act program" (Expand search), "modeling computation using action program" (Expand search), "modeling computation using grant program" (Expand search), "modeling computation using agent program" (Expand search), "modeling computation using ac program" (Expand search), "modeling computation using acc program" (Expand search), "modeling computation using actor 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modeling computation using act program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( modeling computation using act program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("modeling computation using act program") OR ("using python python python programming"))*.
