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"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimized algorithm", "_ optimization algorithms", "_ optimize algorithms", "_ 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: "((((\"_ estimation algorithms\") OR (\"_ optimizer algorithms\"))) OR (\"game optimization algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) OR ( _ optimizer algorithms ))) OR ( game optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") OR ("_ optimizer algorithms"))) OR ("game optimization algorithm"))*.
