Perhaps you should try some spelling variations:
"based computational and complexity from" » "and computational and complexity from" (Expand search), "by computational and complexity from" (Expand search), "based computational fluid complexity from" (Expand search)
"using computational and computing program" » "and computational and computing program" (Expand search), "using computational fluid computing program" (Expand search), "using computational and consulting program" (Expand search), "using computational and computer program" (Expand search), "using computational and computador program" (Expand search), "using computational grid computing program" (Expand search), "using computational fog computing 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: (("using computational and computing program") OR ("based computational and complexity from"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational and computing program\") OR (\"based computational and complexity from\"))".
• Removing quotes may allow a broader search: (( using computational and computing program ) OR ( based computational and complexity from )).
• Adding a wildcard symbol may retrieve word variants: (("using computational and computing program") OR ("based computational and complexity from"))*.
