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