Perhaps you should try some spelling variations:
"modified location optimization algorithms" » "modified location optimisation algorithm", "modified location estimation algorithms", "modified location estimation algorithm", "modified allocation optimization algorithms", "modified static optimization algorithms", "modified carbon optimization algorithms"
"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"

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