Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified adam solution algorithm" » "modified adam evolution algorithm", "modified adam convolution algorithms", "modified adam evolutionary algorithm", "modified df solution algorithm", "modified near solution algorithm", "modified nodal solution algorithm"

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 multiobjective estimation algorithm") OR ("modified adam solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified adam solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified adam solution algorithm"))*.
