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)
"by computational model computing program" » "by computational modeling computing program" (Expand search), "by computational model consulting program" (Expand search), "by computational model computador program" (Expand search), "by computational model computer programs" (Expand search), "_ computational model computing program" (Expand search), "and computational model computing program" (Expand search), "by computational models computing program" (Expand search), "by computational model comprising program" (Expand search), "by computational model 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: "((\"using computational python computer program\") OR (\"by computational model computing program\"))~".
• Removing quotes may allow a broader search: (( using computational python computer program ) OR ( by computational model computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational python computer program") OR ("by computational model computing program"))*.
