Perhaps you should try some spelling variations:
"modified game optimization algorithm" » "modified game optimization algorithms", "modified game optimisation algorithm", "modified game estimation algorithm", "modified stage optimization algorithm", "modified qoe optimization algorithm", "modified market optimization algorithm", "modified male optimization algorithm", "modified adam optimization algorithm"
"modified coverage approximation algorithms" » "modified average approximation 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 optimization algorithm") OR ("modified coverage approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified game optimization algorithm\") OR (\"modified coverage approximation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified game optimization algorithm ) OR ( modified coverage approximation algorithms ))*.
