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"
"d_ optimized algorithm" » "d_ optimized algorithms", "d_ optimizer algorithms", "_ optimize algorithm", "_ optimise algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

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

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