Perhaps you should try some spelling variations:
"modified traces optimisation algorithm" » "modified traces optimization algorithms", "modified traces estimation algorithm", "modified traces estimation algorithms", "modified trace optimisation algorithm"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization 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 traces optimisation algorithm") OR ("modified adaptive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified traces optimisation algorithm ) or ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified traces optimisation algorithm") or ("modified adaptive quantization algorithm"))*.
