Perhaps you should try some spelling variations:
"using computational first example of" » "using computational art example of" (Expand search), "using computational foot example of" (Expand search), "using computational aids example of" (Expand search), "using computational first sample of" (Expand search)
"and computational cost computer program" » "and computational and computer program" (Expand search), "and computational design computer program" (Expand search), "and computational vision computer program" (Expand search), "_ computational cost computer program" (Expand search), "and computational chest computer program" (Expand search), "and computational catt computer program" (Expand search), "and computational test 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: (("and computational cost computer program") OR ("using computational first example of"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational cost computer program\") OR (\"using computational first example of\"))".
• Removing quotes may allow a broader search: (( and computational cost computer program ) OR ( using computational first example of )).
• Adding a wildcard symbol may retrieve word variants: (("and computational cost computer program") OR ("using computational first example of"))*.
