Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
notion optimisation » network optimization
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
co evolution » _ evolution
modified co » modified _, modified df, modified orca

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 notion optimisation algorithm ) OR ( modified co evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified notion optimisation algorithm ) or ( modified co evolution algorithm ))*.
