Perhaps you should try some spelling variations:
"modified caging optimizer algorithm" » "modified caging optimizer algorithms", "modified caging optimized algorithm", "modified caging optimized algorithms", "modified choosing optimizer algorithm"
"modified time approximation algorithms" » "modified one approximation algorithms", "modified _ approximation algorithms", "modified bi1 approximation algorithms", "modified male approximation 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 caging optimizer algorithm") OR ("modified time approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified caging optimizer algorithm ) or ( modified time approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimizer algorithm") or ("modified time approximation algorithms"))*.
