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

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

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