Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, optimized algorithms
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
modified adaptive » modified passive
verified network » certified network, defined network

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

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