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