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