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"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization algorithms"
"_ optimizer 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: (((("_ optimized algorithms") OR ("_ optimizer algorithms"))) OR ("post estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimized algorithms\") OR (\"_ optimizer algorithms\"))) or (\"post estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) OR ( _ optimizer algorithms ))) or ( post estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") OR ("_ optimizer algorithms"))) or ("post estimation algorithms"))*.
