Perhaps you should try some spelling variations:
"advanced computational _ computer program" » "and computational _ computer program" (Expand search), "based computational _ computer program" (Expand search)
"using computational effort example of" » "using computational cost example of" (Expand search), "using computational art example of" (Expand search), "using computational platform example of" (Expand search), "and computational effort example of" (Expand search), "using computational effort sample of" (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: "((\"advanced computational _ computer program\") OR (\"using computational effort example of\"))~".
• Removing quotes may allow a broader search: (( advanced computational _ computer program ) OR ( using computational effort example of ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational _ computer program") OR ("using computational effort example of"))*.
