Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimisation algorithms", "modified adaptive estimation algorithmss", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified passive optimization algorithms"
"modified static optimization algorithm" » "modified static optimisation algorithm", "modified static estimation algorithm", "modified static estimation algorithms", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"

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