Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"_ estimation algorithmss" » "_ estimation algorithms", "_ estimation algorithm", "_ optimization 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.

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