Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified near solution algorithm" » "modified near evolution algorithm", "modified near convolution algorithms", "modified near evolutionary algorithm", "modified seird solution algorithm", "modified adam solution algorithm", "modified nodal solution algorithm", "modified nacl solution algorithm"

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 notion approximation algorithms") OR ("modified near solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion approximation algorithms ) or ( modified near solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion approximation algorithms") or ("modified near solution algorithm"))*.
