Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"mapping learning predation algorithm" » "mapping learning predators algorithm", "mapping learning estimation algorithm", "mapping learning prediction algorithm", "mapping learning emotion algorithm", "machine learning predation algorithm", "enabling 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 optimized algorithm") or ("mapping learning predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("mapping learning predation algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( mapping learning predation algorithm ))*.
