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