Perhaps you should try some spelling variations:
"by computational python computer program" » "by computacional python computer program" (Expand search), "by computacional vpython computer program" (Expand search), "by computacionais python computer program" (Expand search), "_ computational python computer program" (Expand search), "and computational python computer program" (Expand search)
"using computational model computing program" » "and computational model computing program" (Expand search), "using computational modeling computing program" (Expand search), "using computational model consulting program" (Expand search), "using computational model computador program" (Expand search), "using computational model computer programs" (Expand search), "using computational models computing program" (Expand search), "using computational model comprising program" (Expand search), "using computational model computer program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("by computational python computer program") OR ("using computational model computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational python computer program\") OR (\"using computational model computing program\"))*".
• Removing quotes may allow a broader search: (( by computational python computer program ) OR ( using computational model computing program ))*.
