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

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