Perhaps you should try some spelling variations:
"don optimizer algorithms" » "don optimized algorithms", "don optimization algorithms", "dong optimizer algorithms", "doan optimizer algorithms"
"one optimized algorithm" » "one optimized algorithms", "_ optimized algorithm"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("don optimizer algorithms") OR ("one optimized algorithm"))) OR ("post estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"don optimizer algorithms\") OR (\"one optimized algorithm\"))) OR (\"post estimation algorithm\"))".
• Removing quotes may allow a broader search: (((( don optimizer algorithms ) OR ( one optimized algorithm ))) OR ( post estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("don optimizer algorithms") OR ("one optimized algorithm"))) OR ("post estimation algorithm"))*.
