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