Perhaps you should try some spelling variations:
"using computational methods comparing program" » "using computational model comparing program" (Expand search), "and computational methods comparing program" (Expand search), "using computational methods comparison program" (Expand search), "using computational methods comparative program" (Expand search), "using computational method comparison program" (Expand search), "using computational methods computing program" (Expand search), "using computational methods company program" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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 methods comparing program\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( using computational methods comparing program ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational methods comparing program") OR ("using code from python programming"))*.
