Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified adam optimization algorithmss" » "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified adam estimation algorithms", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified _ optimization algorithmss", "modified df optimization algorithmss", "modified near optimization algorithmss"

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 multiobjective estimation algorithm") or ("modified adam optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithm") OR ("modified adam optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified adam optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified adam optimization algorithmss"))*.
