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

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

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