Perhaps you should try some spelling variations:
"modified game optimization algorithms" » "modified game optimisation algorithm", "modified game estimation algorithms", "modified game optimized algorithms", "modified stage optimization algorithms", "modified qoe optimization algorithms", "modified market optimization algorithms", "modified male optimization algorithms", "modified adam optimization algorithms"
"modified risk estimation algorithm" » "modified pose estimation algorithm", "modified bi1 estimation algorithm"

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