Perhaps you should try some spelling variations:
"modified allocation estimation algorithm" » "modified allocation optimization algorithm", "modified motion estimation algorithm"
"modified adaptive quantization algorithmsss" » "modified adaptive ventilation algorithmsss", "modified passive quantization algorithmsss", "modified adaptive quantization algorithms", "modified adaptive quantization algorithmic"

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