Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"enabling learning predators algorithm" » "enabling learning predation algorithm", "enabling marine predators algorithm", "mapping learning predators algorithm"

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: (("enabling learning predators algorithm") or ("modified multiobjective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning predators algorithm") OR ("modified multiobjective optimized algorithms")).
• Removing quotes may allow a broader search: (( enabling learning predators algorithm ) or ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("enabling learning predators algorithm") or ("modified multiobjective optimized algorithms"))*.
