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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("most optimized algorithms") or ("cost optimizer algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("most optimized algorithms") OR ("cost optimizer algorithms"))) OR ("_ estimation algorithms")).
• Removing quotes may allow a broader search: (((( most optimized algorithms ) or ( cost optimizer algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("most optimized algorithms") or ("cost optimizer algorithms"))) or ("_ estimation algorithms"))*.
