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

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

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