Perhaps you should try some spelling variations:
"modified one approximation algorithm" » "modified one approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation algorithm"
"modified learning from algorithm" » "mobile learning from algorithm", "modified caging from algorithm", "modified learning mom algorithm", "modified learning adam 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 learning from algorithm") OR ("modified one approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified learning from algorithm ) or ( modified one approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning from algorithm") or ("modified one approximation algorithm"))*.
