Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
modified adaptive » modified passive
modified time » modified bi1, modified male

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

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