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