Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified game optimized algorithm" » "modified game optimized algorithms", "modified game optimizer algorithms", "modified male optimized algorithm", "modified adam optimized algorithm"

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 objective optimization algorithms\") OR (\"modified game optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified game optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified game optimized algorithm"))*.
