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