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

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: (((("one optimized algorithm") OR ("most optimized algorithm"))) OR ("_ estimation algorithms"))~.
• Removing quotes may allow a broader search: (((( one optimized algorithm ) or ( most optimized algorithm ))) or ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("one optimized algorithm") or ("most optimized algorithm"))) or ("_ estimation algorithms"))*.
