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