Perhaps you should try some spelling variations:
"modified multiobjective predation algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective design algorithm", "modified multiobjective allocation algorithm", "modified multiobjective predators algorithm", "modified multiobjective estimation algorithm"
"modified objective predation algorithms" » "modified objective predators algorithm", "modified objective estimation algorithms", "modified objective approximation algorithms", "modified objective allocation algorithms", "modified objective predators algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective predation algorithms") or ("modified multiobjective predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective predation algorithms") OR ("modified multiobjective predation algorithm")).
• Removing quotes may allow a broader search: (( modified objective predation algorithms ) or ( modified multiobjective predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithms") or ("modified multiobjective predation algorithm"))*.
