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 evolution algorithm" » "modified adam solution algorithm", "modified adam evolutionary algorithm", "modified adam convolution algorithms", "modified df evolution algorithm", "modified near evolution 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 adam evolution algorithm") OR ("modified multiobjective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam evolution algorithm ) or ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam evolution algorithm") or ("modified multiobjective estimation algorithms"))*.
