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