Perhaps you should try some spelling variations:
applications algorithm » approximation algorithm, approximation algorithms
optimizer algorithms » optimized algorithms, optimization algorithms
optimized algorithm » optimized algorithms
world applications » grid applications, mobile applications, toward applications

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( notion ((optimized algorithm) OR (optimizer algorithms)) ) or ( world applications algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( notion ((optimized algorithm) OR (optimizer algorithms)) ) OR ( world applications algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( notion ((optimized algorithm) OR (optimizer algorithms)) ) or ( world applications algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( notion ((optimized algorithm) OR (optimizer algorithms)) ) or ( world applications algorithm ))*.
