Perhaps you should try some spelling variations:
"using computational code computer program" » "and computational code computer program" (Expand search), "using computational model computer program" (Expand search), "using computational cost computer program" (Expand search), "using computational models computer program" (Expand search), "using computational node computer program" (Expand search), "using computational one computer program" (Expand search)
"using coding _ python programming" » "using coping _ python programming" (Expand search), "using coating _ python programming" (Expand search), "using cooking _ 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: "((\"using computational code computer program\") OR (\"using coding _ python programming\"))~".
• Removing quotes may allow a broader search: (( using computational code computer program ) OR ( using coding _ python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational code computer program") OR ("using coding _ python programming"))*.
