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