Perhaps you should try some spelling variations:
"using computational in complex program" » "and computational in complex program" (Expand search), "using computational _ complex program" (Expand search), "using computational 3d complex program" (Expand search), "using computational aids complex program" (Expand search), "using computational in simplex program" (Expand search), "using computational in complex programmes" (Expand search), "using computational in complex prograded" (Expand search)
"by computational and computing program" » "by computational fluid computing program" (Expand search), "by computational and consulting program" (Expand search), "by computational and computer program" (Expand search), "by computational and computador program" (Expand search), "_ computational and computing program" (Expand search), "and computational and computing program" (Expand search), "by computational grid computing program" (Expand search), "by 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: (("by computational and computing program") OR ("using computational in complex program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational and computing program\") OR (\"using computational in complex program\"))".
• Removing quotes may allow a broader search: (( by computational and computing program ) OR ( using computational in complex program )).
• Adding a wildcard symbol may retrieve word variants: (("by computational and computing program") OR ("using computational in complex program"))*.
