Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"one optimizer algorithms" » "one optimized algorithm", "one optimization algorithms"
"don optimized algorithms" » "don optimized algorithm", "don optimization algorithms", "_ optimized 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: (((("one optimizer algorithms") OR ("don optimized algorithms"))) OR ("_ optimisation algorithm"))~.
• Removing quotes may allow a broader search: (((( one optimizer algorithms ) or ( don optimized algorithms ))) or ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("one optimizer algorithms") or ("don optimized algorithms"))) or ("_ optimisation algorithm"))*.
