Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"
"modified adam approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified near approximation algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam approximation algorithms\") OR (\"modified objective allocation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adam approximation algorithms ) OR ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam approximation algorithms") OR ("modified objective allocation algorithm"))*.
