Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimized algorithms"
"post estimation algorithms" » "post estimation algorithm", "post optimisation algorithm", "post approximation algorithms", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ 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: "((((\"_ optimization algorithms\") OR (\"_ optimized algorithm\"))) OR (\"post estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) OR ( _ optimized algorithm ))) OR ( post estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") OR ("_ optimized algorithm"))) OR ("post estimation algorithms"))*.
