Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"done optimized algorithms" » "done optimized algorithm", "done optimization algorithms", "dong optimized algorithms", "one optimized algorithms", "don optimized algorithms"
"_ optimizer algorithms" » "_ optimized algorithm", "_ optimization algorithms", "_ optimized algorithms", "_ optimize algorithms", "_ optimise algorithms"

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

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