Perhaps you should try some spelling variations:
"modeling computation using array program" » "modeling computational using array program" (Expand search), "modeling simulation using array program" (Expand search), "modeling notation using array program" (Expand search), "modeling computations using array program" (Expand search), "modeling computation in array program" (Expand search), "modeling composition using array program" (Expand search), "modeling computation using spray program" (Expand search), "modeling computation using ray program" (Expand search), "modeling computation using warranty program" (Expand search), "modeling computation ring array program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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 array program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( modeling computation using array program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("modeling computation using array program") OR ("using in python python programming"))*.
