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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimisation algorithm\") OR (\"_ estimation algorithms\"))) OR (\"cost optimized algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) OR ( _ estimation algorithms ))) OR ( cost optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") OR ("_ estimation algorithms"))) OR ("cost optimized algorithms"))*.
