Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"machine learning prediction algorithm" » "machine learning predation algorithm", "machine learning predators algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine learning prediction algorithm") or ("modified multiobjective estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machine learning prediction algorithm") OR ("modified multiobjective estimation algorithms")).
• Removing quotes may allow a broader search: (( machine learning prediction algorithm ) or ( modified multiobjective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning prediction algorithm") or ("modified multiobjective estimation algorithms"))*.
