Perhaps you should try some spelling variations:
"and computational python computer program" » "and computacional python computer program" (Expand search), "and computacional vpython computer program" (Expand search), "and computacionais python computer program" (Expand search), "_ computational python computer program" (Expand search)
"based computational codes computing program" » "by computational codes computing program" (Expand search), "based computational code computing program" (Expand search), "based computational models computing program" (Expand search), "based computational model computing program" (Expand search), "based computational codes consulting program" (Expand search), "based computational codes computador program" (Expand search), "based computational codes computer programs" (Expand search), "based computational courses computing 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 codes computing program\") OR (\"and computational python computer program\"))~".
• Removing quotes may allow a broader search: (( based computational codes computing program ) OR ( and computational python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational codes computing program") OR ("and computational python computer program"))*.
