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