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