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