Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"cost optimized algorithm" » "cost optimized algorithms", "cost optimizer algorithms", "most 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 ("cost optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimisation algorithm\") OR (\"_ estimation algorithms\"))) or (\"cost optimized algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) OR ( _ estimation algorithms ))) or ( cost optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") OR ("_ estimation algorithms"))) or ("cost optimized algorithm"))*.
