Perhaps you should try some spelling variations:
"intelligence computational" » "intelligent computational", "intelligence international", "intelligence communication"
"intelligent computation" » "intelligent computational", "intelligent communication", "intelligent computing"
"intelligence computing" » "intelligent computing", "intelligence computer", "intelligent computer"

Try widening your search to All Fields.

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("intelligence computational") OR ("intelligent computation"))) OR ("intelligence computing")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"intelligence computational\") OR (\"intelligent computation\"))) or (\"intelligence computing\"))".
• Removing quotes may allow a broader search: (((( intelligence computational ) OR ( intelligent computation ))) or ( intelligence computing )).
• Adding a wildcard symbol may retrieve word variants: (((("intelligence computational") OR ("intelligent computation"))) or ("intelligence computing"))*.
