Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified global evolution algorithm" » "modified global solution algorithm", "modified global evolutionary algorithm", "modified global convolution algorithms", "modified global solutions algorithm", "modified global production algorithm", "modified global edition 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 global evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion approximation algorithms ) or ( modified global evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion approximation algorithms") or ("modified global evolution algorithm"))*.
