Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
policy optimization » topology optimization
positive evolution » positive solutions
modified positive » 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 positive evolution algorithm ) OR ( modified policy optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified positive evolution algorithm ) or ( modified policy optimization algorithms ))*.
