Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive optimized algorithms", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified pose estimation algorithm" » "modified male estimation algorithm", "modified passive estimation algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified pose estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified pose estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") or ("modified pose estimation algorithm"))*.
