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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified game estimation algorithms") OR ("modified objective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified game estimation algorithms\") OR (\"modified objective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified game estimation algorithms ) OR ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified game estimation algorithms") OR ("modified objective optimization algorithm"))*.
