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