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

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

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