Perhaps you should try some spelling variations:
"d_ optimized algorithms" » "d_ optimizer algorithms", "d_ optimization algorithms", "d_ optimizer algorithmss", "_ optimize algorithms", "_ optimise algorithms"
"_ optimized algorithm" » "_ 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: (((("d_ optimized algorithms") or ("_ optimized algorithm"))) or ("post estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("d_ optimized algorithms") OR ("_ optimized algorithm"))) OR ("post estimation algorithm"))*.
• Removing quotes may allow a broader search: (((( d_ optimized algorithms ) or ( _ optimized algorithm ))) or ( post estimation algorithm ))*.
