Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("active learning predation algorithm") OR ("modified objective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"active learning predation algorithm\") OR (\"modified objective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( active learning predation algorithm ) OR ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("active learning predation algorithm") OR ("modified objective estimation algorithms"))*.
