Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified one approximation algorithms") or ("modified quadratic optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified one approximation algorithms") OR ("modified quadratic optimization algorithm")).
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) or ( modified quadratic optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") or ("modified quadratic optimization algorithm"))*.
