Perhaps you should try some spelling variations:
"same optimized algorithm" » "same optimized algorithms", "same optimizer algorithms"
"some optimized algorithm" » "some optimized algorithms", "some optimizer 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.

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