Perhaps you should try some spelling variations:
"modified adam approximation algorithm" » "modified adam approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"
"modified caging prediction algorithm" » "modified caging predation algorithm", "modified caging predators algorithm", "modified learning prediction algorithm", "modified churn prediction algorithm", "modified cliff prediction 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 caging prediction algorithm") OR ("modified adam approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified caging prediction algorithm ) or ( modified adam approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging prediction algorithm") or ("modified adam approximation algorithm"))*.
