Perhaps you should try some spelling variations:
"post estimation algorithms" » "post optimization algorithms", "post optimisation algorithm", "post approximation algorithms", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimized algorithm", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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