Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"game optimized algorithms" » "game optimizer algorithms", "game optimization algorithms", "game optimizer algorithmss", "same optimized algorithms"
"some optimized algorithm" » "some optimizer 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: (((("some optimized algorithm") OR ("game optimized algorithms"))) OR ("_ estimation algorithms"))~.
• Removing quotes may allow a broader search: (((( some optimized algorithm ) or ( game optimized algorithms ))) or ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("some optimized algorithm") or ("game optimized algorithms"))) or ("_ estimation algorithms"))*.
