Perhaps you should try some spelling variations:
approximations algorithms » approximation algorithms, approximation algorithm
rough approximations » one approximation
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
made evolution » sales evolution, time evolution
modified made » modified male, modified adam, modified df

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 made evolution algorithm ) OR ( modified rough approximations algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified made evolution algorithm ) or ( modified rough approximations algorithms ))*.
