Perhaps you should try some spelling variations:
"post estimation algorithms" » "post estimation algorithm", "post optimization algorithms", "post optimisation algorithm", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"
"done optimized algorithm" » "done optimized algorithms", "dong optimized algorithm", "one optimized algorithm", "don optimized 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 ("_ optimizer algorithms"))) or ("post estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("done optimized algorithm") OR ("_ optimizer algorithms"))) OR ("post estimation algorithms")).
• Removing quotes may allow a broader search: (((( done optimized algorithm ) or ( _ optimizer algorithms ))) or ( post estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") or ("_ optimizer algorithms"))) or ("post estimation algorithms"))*.
