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