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 optimizer algorithms" » "modified lighting optimized algorithms", "modified lighting optimized algorithm", "modified lighting optimization algorithms", "modified caging optimizer algorithms"

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 quantization algorithm") OR ("modified lighting optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) or ( modified lighting optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") or ("modified lighting optimizer algorithms"))*.
