Perhaps you should try some spelling variations:
"modeling computation using time program" » "modeling computational using time program" (Expand search), "modeling simulation using time program" (Expand search), "modeling notation using time program" (Expand search), "modeling computations using time program" (Expand search), "modeling computation in time program" (Expand search), "modeling composition using time program" (Expand search), "modeling computation using life program" (Expand search), "modeling computation using home program" (Expand search), "modeling computation using care 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 time program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( modeling computation using time program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("modeling computation using time program") OR ("using python python python programming"))*.
