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