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