Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified near solution algorithms" » "modified near solution algorithm", "modified near evolution algorithm", "modified near convolution algorithms", "modified seird solution algorithms", "modified adam solution algorithms", "modified nodal solution algorithms", "modified nacl solution algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified coverage approximation algorithms") OR ("modified near solution algorithms"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) or ( modified near solution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithms") or ("modified near solution algorithms"))*.
