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

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("done optimized algorithm") or ("one optimizer algorithms"))) or ("post estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("done optimized algorithm") OR ("one optimizer algorithms"))) OR ("post estimation algorithm")).
• Removing quotes may allow a broader search: (((( done optimized algorithm ) or ( one optimizer algorithms ))) or ( post estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") or ("one optimizer algorithms"))) or ("post estimation algorithm"))*.
