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