Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified adam optimized algorithms" » "modified adam optimized algorithm", "modified adam optimizer algorithms", "modified adam optimization algorithms", "modified df optimized algorithms", "modified near optimized algorithms"

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

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