Perhaps you should try some spelling variations:
"active learning predation algorithm" » "active learning predators algorithm", "active learning estimation algorithm", "active learning prediction algorithm", "active learning emotion algorithm", "machine learning predation algorithm"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution 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: "((\"active learning predation algorithm\") OR (\"modified objective solution algorithm\"))~".
• Removing quotes may allow a broader search: (( active learning predation algorithm ) OR ( modified objective solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("active learning predation algorithm") OR ("modified objective solution algorithm"))*.
