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

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