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