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