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)
"using computational _ computing program" » "and computational _ computing program" (Expand search), "using computational _ consulting program" (Expand search), "using computational _ computador program" (Expand search), "using computational _ computer programs" (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 _ computing program") OR ("advanced computation in computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational _ computing program\") OR (\"advanced computation in computer program\"))".
• Removing quotes may allow a broader search: (( using computational _ computing program ) OR ( advanced computation in computer program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational _ computing program") OR ("advanced computation in computer program"))*.
