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

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

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