Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimizer algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimisation algorithm", "_ approximation algorithms"
"post optimized algorithms" » "post optimized algorithm", "post optimizer algorithms", "most optimized algorithms", "cost optimized 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: (((("_ optimization algorithms") or ("post optimized algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimization algorithms") OR ("post optimized algorithms"))) OR ("_ estimation algorithms")).
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) or ( post optimized algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") or ("post optimized algorithms"))) or ("_ estimation algorithms"))*.
