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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimiser algorithms") OR ("_ optimize algorithms"))) OR ("game estimation algorithms"))~.
• Removing quotes may allow a broader search: (((( _ optimiser algorithms ) or ( _ optimize algorithms ))) or ( game estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimiser algorithms") or ("_ optimize algorithms"))) or ("game estimation algorithms"))*.
