Perhaps you should try some spelling variations:
"one optimization algorithms" » "one estimation algorithms", "one estimation algorithm", "one optimized algorithms", "qoe optimization algorithms", "game optimization algorithms", "_ optimization algorithms"
"_ optimisation algorithm" » "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"d_ optimized algorithm" » "d_ optimized algorithms", "d_ optimizer algorithms", "_ optimized algorithm", "_ optimize algorithm", "_ optimise 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: (((("d_ optimized algorithm") or ("one optimization algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("d_ optimized algorithm") OR ("one optimization algorithms"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( d_ optimized algorithm ) or ( one optimization algorithms ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimized algorithm") or ("one optimization algorithms"))) or ("_ optimisation algorithm"))*.
