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