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