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