Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithm", "modified adaptive optimized algorithms", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified caging estimation algorithms" » "modified caging estimation algorithm", "modified caging optimisation algorithm", "modified caging approximation algorithms", "modified lighting estimation algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimization algorithms") or ("modified caging estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified caging estimation algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified caging estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") or ("modified caging estimation algorithms"))*.
