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

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