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 optimized algorithms" » "modified made optimized algorithm", "modified made optimizer algorithms", "modified made optimization algorithms", "modified male optimized algorithms", "modified adam optimized algorithms", "modified df optimized algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified made optimized algorithms\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified made optimized algorithms ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made optimized algorithms") OR ("modified multiobjective optimization algorithm"))*.
