Perhaps you should try some spelling variations:
"advanced computation in computer program" » "advanced computations in computer program" (Expand search), "advanced computational in computer program" (Expand search), "advance computational in computer program" (Expand search), "advanced computation and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced imputation in computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"based computational in complexity from" » "and computational in complexity from" (Expand search), "by computational in complexity from" (Expand search), "based computational and complexity from" (Expand search), "based computational _ complexity from" (Expand search), "based computational 3d complexity from" (Expand search), "based computational on complexity from" (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: (("advanced computation in computer program") OR ("based computational in complexity from"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computation in computer program\") OR (\"based computational in complexity from\"))".
• Removing quotes may allow a broader search: (( advanced computation in computer program ) OR ( based computational in complexity from )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computation in computer program") OR ("based computational in complexity from"))*.
