Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
solutions algorithms » solution algorithm, evolution algorithm, convolution algorithms
notion optimization » network optimization, policy optimization, allocation optimization
passive solutions » positive solutions
modified passive » modified adaptive

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 passive solutions algorithms ) OR ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive solutions algorithms ) or ( modified notion optimization algorithms ))*.
