Perhaps you should try some spelling variations:
"don optimizer algorithms" » "don optimized algorithm", "don optimization algorithms", "dong optimizer algorithms", "doan optimizer algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization algorithms"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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: "((((\"don optimizer algorithms\") OR (\"_ optimized algorithms\"))) OR (\"post estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( don optimizer algorithms ) OR ( _ optimized algorithms ))) OR ( post estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("don optimizer algorithms") OR ("_ optimized algorithms"))) OR ("post estimation algorithm"))*.
