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