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