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