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

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: (((("don optimized algorithm") OR ("don optimizer algorithms"))) OR ("_ optimisation algorithm"))~.
• Removing quotes may allow a broader search: (((( don optimized algorithm ) or ( don optimizer algorithms ))) or ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("don optimized algorithm") or ("don optimizer algorithms"))) or ("_ optimisation algorithm"))*.
