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