Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified passive optimizer algorithms" » "modified passive optimized algorithms", "modified passive optimized algorithm", "modified passive optimization algorithms", "modified adaptive optimizer 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 passive optimizer algorithms") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified passive optimizer algorithms ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimizer algorithms") or ("modified multiobjective optimization algorithm"))*.
