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