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"
"post optimized algorithm" » "post optimized algorithms", "post optimizer algorithms", "most optimized algorithm", "cost optimized algorithm"

Try widening your search to All Fields.

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

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