You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced estimation on computer program") OR ("advanced simulation and computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced estimation on computer program\") OR (\"advanced simulation and computation program\"))".
• Removing quotes may allow a broader search: (( advanced estimation on computer program ) OR ( advanced simulation and computation program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced estimation on computer program") OR ("advanced simulation and computation program"))*.
