Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified mild solutions algorithm" » "modified mild solution algorithm", "modified mild evolution algorithm", "modified mild evolutionary algorithm", "modified time solutions algorithm", "modified male solutions algorithm", "modified seird solutions algorithm", "modified bi1 solutions 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 mild solutions algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified mild solutions algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified mild solutions algorithm") or ("modified multiobjective optimization algorithm"))*.
