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

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: (((("_ optimized algorithms") or ("_ optimize algorithms"))) or ("game optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimized algorithms") OR ("_ optimize algorithms"))) OR ("game optimisation algorithm")).
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) or ( _ optimize algorithms ))) or ( game optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") or ("_ optimize algorithms"))) or ("game optimisation algorithm"))*.
