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