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

Try widening your search to All Fields.

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 optimized algorithm") OR ("game optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimization algorithm") OR ((("game optimized algorithm") OR ("game optimized algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ optimization algorithm\") or (((\"game optimized algorithm\") OR (\"game optimized algorithms\"))))".
• Removing quotes may allow a broader search: (( _ optimization algorithm ) or ((( game optimized algorithm ) OR ( game optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimization algorithm") or ((("game optimized algorithm") OR ("game optimized algorithms"))))*.
