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

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