Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective optimized algorithms", "modified multiobjective optimization algorithms"
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimisation algorithm", "modified adaptive approximation algorithms", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms", "modified passive estimation algorithms"

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 algorithms") OR ("modified adaptive estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) or ( modified adaptive estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") or ("modified adaptive estimation algorithms"))*.
