Perhaps you should try some spelling variations:
"game optimization algorithm" » "game optimization algorithms", "game optimisation algorithm", "game estimation algorithm", "stage optimization algorithm", "qoe optimization algorithm", "market optimization algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise algorithms"

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

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