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