Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective solution algorithm"
"active learning predation algorithm" » "active learning predators algorithm", "active learning estimation algorithm", "active learning prediction algorithm", "active learning emotion algorithm", "machine learning predation algorithm"

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: "((\"active learning predation algorithm\") OR (\"modified objective allocation algorithm\"))~".
• Removing quotes may allow a broader search: (( active learning predation algorithm ) OR ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("active learning predation algorithm") OR ("modified objective allocation algorithm"))*.
