Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"mobile learning predation algorithm" » "mobile learning predators algorithm", "mobile learning prediction algorithm", "mobile 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: (("mobile learning predation algorithm") OR ("modified multiobjective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mobile learning predation algorithm\") OR (\"modified multiobjective estimation algorithm\"))".
• Removing quotes may allow a broader search: (( mobile learning predation algorithm ) OR ( modified multiobjective estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mobile learning predation algorithm") OR ("modified multiobjective estimation algorithm"))*.
